+* Version 1.7 can't create wp-config.php when installing with WordPress 4.0
+
+	When install process notices that there's no wp-config.php, it tries to
+	create one from wp-config-sample.php. During that time, WordPress unsets
+	global $wpdb and calls require_wp_db() function.
+	That function newly instantiates wpdb class. SQLite Integration has no
+	way of intercepting that process.

+2015-03-18  KOJIMA Toshiyasu
+
+	* version 1.8.1 bugfix release.
+
+	* pdoengine.class.php: bugfix. database file existent chech doesn't
+	  work properly, which causes installation problem.
+
+2015-03-06  KOJIMA Toshiyasu
+
+	* version 1.8 release.
+
+	* readme.txt, readme-ja.txt: updated.
+
+	* query_create.class.php: fixed the index query regexp.
+
+	* query.class.php: added 'orderby_callback' method.
+	  This is a workaround for PHP 5.2.x compatibility issue.
+
+2015-03-05  KOJIMA Toshiyasu
+
+	* pdodb.class.php: removed the unnecessary require directive.
+
+	* pdoengin.class.php: revised install process algorithm.
+	  Database directory and file check was too late.
+	  Changed the database directory permission.
+
+2014-10-01  KOJIMA Toshiyasu
+
+	* pdoengine.class.php: revised pdoengine class constructor definition
+	  in order to reuse the PDO instance.
+
+	* pdodb.class.php, pdoengine.class.php: moved the foreign key check
+	  from PDODB class to PDOEngine class init() method.
+
+	* functions.php, functions-5-2.php: check if PDO instance is not null
+	  to avoid displaying Zend debugger/Xdebug messages. If null, constructor
+	  executes wp_die() function.
+
+	* query_create.class.php: changed the data type rewriting method.
+	  When a field name is the same as data type, e.g. "date" or "timestamp",
+	  add a single quote to the field name and avoid to be rewritten.
+	  This works only if the field name is on the top of the line, according
+	  to the rule of dbDelta() function.
+
+	  Added the new function to quote illegal field name, e.g. "default" or
+	  "values", for SQLite. This is for the plugins that use those names to
+	  create tables without errors.
+
+2014-09-05  KOJIMA Toshiyasu
+
+	* version 1.7 release.
+	* update readme.txt and readme-ja.txt.
+
+2014-08-29  KOJIMA Toshiyasu
+
+	* Added ChangeLog and BUGS files.

 == Description ==

-このプラグインは[SQLite](http://www.sqlite.org/)を使ってWordPressを運用するためのものです。MySQLデータベース・サーバを用意する必要はありません。SQLiteは自己完結的で、サーバを必要とせず、トランザクションをサポートしたデータベース・エンジンです。MySQLのようにたくさんの拡張機能を持たないかわりに、小規模から中規模のトラフィックがあるウェブサイトに適しています。
+このプラグインを使うと、MySQL データベースサーバがなくても WordPress のサイトを作ることができます。必要なものは、Apache か、同等のウェブサーバと、PDO エクステンションが使える PHP だけです。WordPress のアーカイブとこのプラグインがあれば、それだけで WordPress サイトを試すことができます。

-SQLite Integrationはラッパ・プログラムです。WordPressとSQLiteの間に入って、やり取りを中継し、次のように動作します。
+SQLite Integration は [PDO for WordPress](http://wordpress.org/extend/plugins/pdo-for-wordpress) プラグインの後継です。後者は残念なことに、もうメンテナンスされていないようです。SQLite IntegrationはPDO for WordPressの基本的なアイディアと構造を借りて、より多くの機能とユーティリティを追加しました。

-1. WordPressからMySQLに発行されるSQLステートメントをインターセプトします
-2. それをSQLiteが実行できる形に書き換えます
-3. SQLiteに渡します
-4. SQLiteから結果を受け取ります
-5. 必要なら、WordPressが望む形式にフォーマットしなおします
-6. WordPressに結果を返します
+= 特徴 =

-WordPressはMySQLと話していると思っていて、背後で何が起こっているかは知りません。実際にはSQLiteと話しているのですが、WordPressはいつもの通り仕事をします。
+SQLite Integration はデータベースアクセスを制御するためのプログラムです。だから、他のプラグインとは違います。WordPress をインストールするときに使わなければなりません。インストールのセクションを参照してください。[SQLite Integration(ja)](http://dogwood.skr.jp/wordpress/sqlite-integration-ja/)をご覧になると、もっと詳しい説明を読むことができます。

-SQLite Integrationは[PDO for WordPress](http://wordpress.org/extend/plugins/pdo-for-wordpress)プラグインの後継です。後者は残念なことに、もうメンテナンスされていないようです。SQLite IntegrationはPDO for WordPressの基本的なアイディアと構造を借りて、より多くの機能とユーティリティを追加しました。
+インストールに成功したら、MySQL を使う他の WordPress と同じように使うことができます。オプションとして、一時的に MySQL を使い、また SQLite に戻るというような使い方ができます。開発のときに、MySQL のないローカルマシンでサイトのテストをすることもできるでしょう。

-= Features =
+インストールが終わったら、このプラグインを有効化することができます(必須ではありませんが、お勧めします）。そうすると、サーバやインストールされたプラグインについての情報を見ることができるようになります。

-SQLite Integrationは普通の「プラグイン」ではありません。WordPressをインストールするときに使います。そのため、少し準備が必要です。インストールのセクションを参照してください。[SQLite Integration Page](http://dogwood.skr.jp/wordpress/sqlite-integration/)をご覧になると、もっと詳しい説明を読むことができます。
+= システム要件 =

-インストールに成功したら、MySQLを使う他のWordPressと同じように使うことができます。オプションとして、管理パネルでこのプラグインを有効化することができます。有効化すると有益な情報と説明を見ることができます。これは必須ではありませんが、お勧めします。
+* PHP 5.2 以上で PDO extension が必要です(PHP 5.3 以上をお勧めします)。
+* PDO SQLite ドライバがロードされている必要があります。

-= Backward Compatibility =
+= 後方互換性 =

 現在[PDO for WordPress](http://wordpress.org/extend/plugins/pdo-for-wordpress)をお使いの場合は、データベースを移行することができます。インストールのセクションをご覧ください。

+* 日本語(kjmtsh)
+* スペイン語(Pablo Laguna)

-まず、WordPressのインストールを準備しなければなりません。Codexの[Installing Wordpress ](http://codex.wordpress.org/Installing_WordPress)をご覧ください。
+== インストール ==

-必要要件をチェックし、WordPressのアーカイブを展開したら、wp-config-sample.phpをwp-config.phpにリネームして、[Codex page](http://codex.wordpress.org/Editing_wp-config.php)に書いてあるように、少し編集する必要があります。データベースの設定*以外*の部分を設定してください。
+より詳細な情報は、[SQLite Integration(ja)](http://dogwood.skr.jp/wordpress/sqlite-integration-ja/)をご覧ください。

-終わったら、オプションの設定を書き加えることができます。次の説明に従ってください。
+= 準備 =

-* デフォルト(wp-content/database)とは違うディレクトリにSQLiteデータベース・ファイルを置きたい場合は、次の行を追加してください(最後のスラッシュを忘れずに)。
-	
-	`define('DB_DIR', '/home/youraccount/database_directory/');`
-	
-	注意: PHPスクリプトがこのディレクトリを作ったり、中にファイルを書き込んだりする権限を持っていることが必要です。
-	
-* デフォルト(.ht.sqlite)とは違うデータベース・ファイル名を使いたい場合は、次の行を追加してください。
-	
-	`define('DB_FILE', 'database_file_name');`
-	
-	注意: PDO for WordPressをお使いの方は、「データベースを移行する」のセクションをご覧ください。
+1. 最新の WordPress アーカイブとこのプラグインをダウンロードして、ローカルマシンに展開します。
+2. sqlite-integration フォルダを wordpress/wp-content/plugins フォルダに移動します。
+3. sqlite-integration フォルダの中にある db.php ファイルを wordpress/wp-content フォルダにコピーします。
+4. wordpress/wp-config-sample.php ファイルを wordpress/wp-config.php とリネームします。

-	よくわからない場合は、何も追加する必要はありません。
+= 基本的な設定 =

-wp-config.phpの準備が終わったら、次のステップに進みます。
+wp-config.php ファイルを開き、下のセクションを編集します。

-1. プラグインのアーカイブを展開します。
+* 認証用ユニークキー
+* WordPressデータベーステーブルの接頭辞
+* ローカル言語(日本語版では、jaがすでに設定されています)

-2. アーカイブに含まれるdb.phpファイルをwp-contentディレクトリに移動(またはコピー)してください。
+Codex の[wp-config.php の編集](http://wpdocs.sourceforge.jp/wp-config.php_%E3%81%AE%E7%B7%A8%E9%9B%86)を参照してください。

-3. sqlite-wordpressディレクトリをwp-content/plugin/ディレクトリの下に移動してください。
+= 5 分もかからないインストール =

-  `wordpress/wp-contents/db.php`
-	
-	と、
-	
-  `wordpress/wp-contents/sqlite-integration`
-	
-	のようになります。
+wordpress フォルダをサーバにアップロードして、ブラウザでアクセスすると、インストールが始まります。ブログ名などを入力してインストールすれば終了です。ブログをお楽しみください。

-さあ、これでお終いです。ディレクトリの構造をそのままに、あなたのサーバにアップロードして、お好きなブラウザでwp-admin/install.phpにアクセスしてください。WordPressのインストールが始まります。Enjoy blogging!
+= オプション設定 =

-= Migrate your database to SQLite Integration =
+wp-config.php に設定を書き込むと、デフォルトの設定を変更することができます。SQLite データベースファイル名を変更したい場合は（デフォルトは .ht.sqlite です）、下の 1 行を加えてください。

-一番よい方法は、次のようにすることです。
+`define('DB_FILE', 'your_database_name');`

-1. データをエクスポートする。
+SQLite データベースファイルが置かれるディレクトリを変更したい場合は、次の行を追加してください。

+`define('DB_DIR', '/home/youraccount/database_directory/');`
+
+どちらか片方だけでも、両方でも変更できます。
+
+= このプラグインを削除せずに MySQL を使う =
+
+MySQL を使いたいときは、次の行を wp-config.php に追加してください。
+
+`define('USE_MYSQL', true);`
+
+もちろん、これだけでは足りません。データベースサーバやユーザ名、パスワードなども設定してください。この行を追加して、最初にサイトにアクセスすると、WordPress のインストールが始まります。MySQL でのインストールを終えてください。おわかりのように、SQLite のデータは自動的に MySQL に引き継がれることはありません。
+
+SQLite に戻りたいときには、この行を次のように変更するか、この行を削除してください。
+
+`define('USE_MYSQL', false);`
+
+= PDO for WordPress から SQLite Integration にデータベースを移行する =
+
+現在、PDO for WordPress をお使いなら、データベースを SQLite Integration に移行することができます。お勧めは下のようにすることです。より詳細な情報については、[SQLite Integration(ja)](http://dogwood.skr.jp/wordpress/sqlite-integration-ja/)を参照してください。
+
+1. 現在のデータをエクスポートする。
 2. 最新のWordPressを、SQLite Integrationを使って新規インストールする。
-
 3. WordPress Importerを使って以前のデータをインポートする。

-何らかの理由で、データがエクスポートできない場合は、次の方法を試すことができます。
+何らかの理由で、データがエクスポートできない場合は、上のサイトをご覧ください。別の方法を読むことができます。

-1. あなたのMyBlog.sqliteがWordPressの必要とするテーブルを全て含んでいるかどうかチェックしてください。[SQLite Manager Mozilla Addon](https://addons.mozilla.org/en-US/firefox/addon/sqlite-manager/)のようなユーティリティが必要かもしれません。また、Codexの[Database Description](http://codex.wordpress.org/Database_Description)を参照してください。
+== よくある質問 ==

-2. MyBlog.sqliteとdb.phpファイルをバックアップしてください。
+= 「データベース接続エラー」でインストールが止まります =

-3. あなたのMyBlog.sqliteを.ht.sqliteにリネームするか、または、wp-config.phpに次の行を追加してください。
-	
-	`define('FQDB', 'MyBlog.sqlite');`
-
-4. wp-content/db.phpをSQLite Integrationに含まれている同名のファイルと入れ替えてください。
-
-これでおしまいです。忘れずに必要要件とWordPressのバージョンをチェックしてください。*SQLite IntegrationはWordPress 3.2.x以前のものでは動作しません。*

+# SQLite Integration
+Contributors: kjmtsh
+Plugin Name: SQLite Integration
+Plugin URI: http://dogwood.skr.jp/wordpress/sqlite-integration/
+Tags: database, SQLite, PDO
+Author: Kojima Toshiyasu
+Author URI: http://dogwood.skr.jp/
+Requires at least: 3.3

+
+SQLite Integration is the plugin that enables WordPress to use SQLite. If you want to build a WordPress website with it, this plugin is for you.
+
+## Description
+
+This plugin enables you to create WordPress based web sites without MySQL database server. All you've got to prepare is the Apache web server or the like and PHP with PDO extension. WordPress archive and this plugin in hand, you can build a WordPress web site out of the box.
+
+SQLite Integration is a successor to [PDO for WordPress](http://wordpress.org/extend/plugins/pdo-for-wordpress) plugin, which unfortunately enough, doesn't seem to be maintained any more. SQLite Integration uses the basic idea and structures of that plugin and adds some utilities with more features.
+
+### Features
+
+SQLite Integration is a database access engine program, which means it's not like the other plugins. It must be used to install WordPress. Please read the install section. And see more detailed instruction in the [SQLite Integration Page](http://dogwood.skr.jp/wordpress/sqlite-integration/).
+
+Once you succeed in installing WordPress, you can use it just like the other systems using MySQL. Optionally, this plugin provides the feature to temporarily change the database to MySQL and come back to SQLite, which may help developers test their sites on the local machines without MySQL.
+
+After you finish installing, you can activate this plugin (this is optional but I recommend you to). And you can see some instructions and useful information on your server or your installed plugins.
+
+### System Requirements
+
+* PHP 5.2 or newer with PDO extension (PHP 5.3 or newer is better).
+* PDO SQLite driver must be loaded.
+
+### Backward Compatibility
+
+If you are using 'PDO for WordPress', you can migrate your database to this plugin. Please check the install section.
+
+### Support (outdated)
+
+Please contact us with the methods below:
+
+1. Post to [Support Forum](http://wordpress.org/support/plugin/sqlite-integration/).
+2. Visit the [SQLite Integration Page](http://dogwood.skr.jp/wordpress/sqlite-integration/)(in English) or [SQLite Integration(ja) Page](http://dogwood.skr.jp/wordpress/sqlite-integration-ja/)(in Japanese) and leave a message there.
+
+### Notes about Support
+
+WordPress.org doesn't officially support using any other database than MySQL. So you will have no supports from WordPress.org. Even if you post to the general Forum, you'll have few chances to get the answer. And if you use patched plugins, you will have no support from the plugin author(s), eithter. I will help you as much as I can, but take your own risk, please.
+
+### Translation
+
+Documentation is written in English. If you translate it into your language, please let me know.
+
+* Japanese (kjmtsh)
+* Spanish (Pablo Laguna)
+
+## Installation
+
+For more detailed instruction, please visit [SQLite Integration](http://dogwood.skr.jp/wordpress/sqlite-integration/).
+
+### Preparation
+
+1. Download the latest WordPress archive and this plugin. And expand them on your machine.
+2. Move sqlite-integration folder to wordpress/wp-content/plugins folder.
+3. Copy db.php file in sqlite-integratin folder to wordpress/wp-content folder.
+4. Rename wordpress/wp-config-sample.php to wordpress/wp-config.php.
+
+### Basic settings
+
+Open wp-config.php and edit the section below:
+
+* Authentication Unique keys and Salts
+* WordPress Database Table prefix
+* WordPress Localized Language
+
+See also [Editing wp-config.php](http://codex.wordpress.org/Editing_wp-config.php) in the Codex. Note that you don't have to write your database server, user name, user password or etc...
+
+### Less than 5 minutes installation
+
+Upload everything (keeping the directory structure) to your server and access the wp-admin/install.php with your favorite browser, and WordPress installation process will begin. Enjoy your blogging!
+
+### Optional settings
+
+You can change some default settings with the directives in wp-config.php.If you change the SQLite database file name (default is .ht.sqlite) to others, add the next line in your wp-config.php.
+
+`define('DB_FILE', 'your_database_name');`
+
+If you change the directory where the SQLite database is put, add the next line in your wp-config.php.
+
+`define('DB_DIR', '/home/youraccount/database_directory/');`
+
+You can change either of them or both of them.
+
+### Use MySQL without uninstalling this plugins
+
+If you want to use MySQL, add the next line in your wp-config.php.
+
+`define('USE_MYSQL', true);`
+
+Of course, this is not enough. You must give your database server address, user name, passowrd or etc... in the same file. After you add that line and access your web site for the first time, WordPress installer will begin. Then you must finish setting MySQL database. As you know, data in the SQLite database is not automatically migrated to MySQL.
+
+If you want to use SQLite again, change the line in wp-config.php as below or just remove this line.
+
+`define('USE_MYSQL', false);`
+
+### For PDO for WordPress users
+
+If you are using PDO for WordPress now, you can migrate your database to SQLite Integration. I recommend the way below. See more detailed instruction [SQLite Integration](http://dogwood.skr.jp/wordpress/sqlite-integration/).
+
+1. Export your data from current database.
+2. Install latest WordPress with SQLite Integration.
+3. Import the old data.
+
+If export or import fails for some reason, please visit our site and try another way described there.
+
+## Frequently Asked Questions
+
+### Install stops with 'Error establishing a database connection'
+
+It is required that you should prepare wp-config.php manually. If you try to make WordPress create wp-config.php, you'll get that message and can't continue install process.
+
+### Database file is not created
+
+The reason of failure in creating directory or files is often that PHP is not allowed to craete them. Please check your server setting or ask the administrator.
+
+### Such and such plugins can't be activated or doesn't seem to work properly
+
+Some of the plugins, especially cache plugins or database maintenace plugins, are not compatible with this plugin. Please activate SQLite Integration and see the known limitations section in this document or visit the [SQLite Integration](http://dogwood.skr.jp/wordpress/sqlite-integration/) for more detailed information.
+
+### I don't want the admin menu and documentation
+
+Just deactivate the plugin, and you can remove them. Activation and deactivation affect only admin menu. If you want to remove all the plugin files, just delete it.
+
+## Screenshots
+
+1. System Information tells you your database status and installed plugins compatibility.
+
+## Known Limitations
+
+Many of the other plugins will work fine with this plugin. But there are some you can't use. Generally speaking, the plugins that manipulate database not with WordPress' APIs but with MySQL or MySQLi native drivers from PHP might cause the problem.
+
+These are some examples:
+
+You can't use these plugins because they create the same file that this plugin uses.
+
+* W3 Total Cache
+* DB Cache Reloaded Fix
+* HyperDB
+
+You may be able to use 'WP Super Cache' or 'Quick Cache' instead of them. I don't mean to recommend them and give no warranty at all.
+
+You can't use these plugins, because they are using MySQL specific features that SQLite Integration can't emulate.
+
+* Yet Another Related Posts
+* Better Related Posts
+
+You may be able to use 'WordPress Related Posts' or 'Related Posts' instead of them. Probably there are more, I'm afraid. If you find one, please let me know.
+
+There are some among the incompatible plugins, which work fine by rewriting some codes. I give information about them and provide the patch files on [Plugins](http://dogwood.skr.jp/wordpress/plugins/).
+
+This plugin doesn't support 'WP_PLUGIN_URL' constant.
+
+## Upgrade Notice
+
+WordPress 4.1.1 compatibility is checked and some bugs are fixed. Upgrade is recommended. When auto upgrading fails, please try manual upgrade via FTP.

-SQLite Integration is the plugin that enables WordPress to use SQLite. If you want to build a WordPress website with it, this plugin is for you.
-
-== Description ==
-
-This plugin enables WordPress to work with [SQLite](http://www.sqlite.org/). You don't have to prepare MySQL database server and its configuration. SQLite is a self-contained, serverless, transactional SQL database engine. It is not a full-featured database system like MySQL or PostgreSQL, but it best fits for low to medium traffic websites.
-
-SQLite Integration is a kind of wrapper program, which is placed between WordPress and SQLite database and works as a mediator. It works as follows:
-
-1. Intercepts the SQL statement for MySQL from WordPress
-2. Rewrites it for SQLite to execute
-3. Give it to SQLite
-4. Gets the results from SQLite
-5. Formats the results as WordPress wants, if necessary
-6. Give the results back to WordPress
-
-WordPress thinks she talks with MySQL and doesn't know what has happened in the background. She really talks with SQLite and will be happy with it.
-
-SQLite Integration is a successor to [PDO for WordPress](http://wordpress.org/extend/plugins/pdo-for-wordpress) plugin, which unfortunately enough, doesn't seem to be maintained any more. SQLite Integration uses the basic idea and structures of that plugin and adds some more features or some utilities.

-
-Documentation is written in English. Japanese catalog file and .pot file are included in the archive. If you translate it into your language, please let me know.
-
-== Installation ==
-
-This plugin is *not* like the other plugins. You can't install and activate it on the plugin administration panel.
-
-First of all, you've got to prepare WordPress installation. See [Installing Wordpress ](http://codex.wordpress.org/Installing_WordPress) section in the Codex.
-
-After checking the prerequisites and unzipping the WordPress archive file, you must rename wp-contig-sample.php file to wp-config.php and do some editting as the [Codex page](http://codex.wordpress.org/Editing_wp-config.php) says. Please follow the instructions *except* the database settings.
-
-When you finish, you can add optional settings. Follow the steps below:
-
-* If you want to put the SQLite database file to the directory different from the default setting (wp-content/database), you can add the line below (don't forget to add a trailing slash):
-
-	`define('DB_DIR', '/home/youraccount/database_directory/');`
-
-	Note: Your PHP scripts must be able to create that directory and files in it.
-
-* If you want to change the database file name to the one different from the default (.ht.sqlite), you can add the line below:
-
-	`define('DB_FILE', 'database_file_name');`
-
-	Note: If you are using 'PDO for WordPress' plugin, see also 'Migrating your database' section.
-
-	If you don't understand well, you don't have to add any of the lines above.
-
-After you finish preparing wp-config.php, follow the next steps:
-
-1. Unzip the plugin archive file.
-
-2. Move db.php file contained in the archive to wp-content directory.
-
-3. Move the sqlite-integration directory to wp-content/plugin/ directory.
-
-  `wordpress/wp-contents/db.php`
-
-	and
-	
-  `wordpress/wp-contents/sqlite-integration`
-
-  respectively.
-
-OK. This is all. Upload everything (keeping the directory structure) to your server and access the wp-admin/install.php with your favorite browser, and WordPress installation process will begin. Enjoy your blogging!
-
-= Migrate your database to SQLite Integration =
-
-If you are using PDO for WordPress now, you can migrate your database to SQLite Integration. You don't have to reinstall WordPress. Please follow the next steps:
-
-1. Check if your MyBlog.sqlite file contains all the tables required by WordPress. You have to use a utility software like [SQLite Manager Mozilla Addon](https://addons.mozilla.org/en-US/firefox/addon/sqlite-manager/). See also [Database Description](http://codex.wordpress.org/Database_Description) in Codex.
-
-2. Backup your MyBlog.sqlite and db.php files.
-
-3. EITHER rename your MyBlog.sqlite to .ht.sqlite OR add the next line in wp-config.php file.
-	
-	`define('FQDB', 'MyBlog.sqlite');`
-
-4. Overwrite your wp-content/db.php with the db.php file contained in SQLite Integration archive.
-
-That's all. Don't forget to check the requirement and your WordPress version. *SQLite Integration doesn't work with WordPress version 3.2.x or lesser*.
-

-Many of the other plugins will work fine with this plugin. But there are some you can't use. Generally speaking, the plugins that manipulate database not with WordPress functions but with Mysql or Mysqli native drivers from PHP might cause the problem.
-
-These are other examples:
-
-= You can't use these plugins because they create the same file that this plugin uses: =
-
-* [W3 Total Cache](http://wordpress.org/extend/plugins/w3-total-cache/)
-* [DB Cache Reloaded Fix](http://wordpress.org/extend/plugins/db-cache-reloaded-fix/)
-* [HyperDB](http://wordpress.org/extend/plugins/hyperdb/)
-
-= You can't use some of the plugins, because they are using MySQL specific features that SQLite can't emulate. For example: =
-
-* [Yet Another Related Posts](http://wordpress.org/extend/plugins/yet-another-related-posts-plugin/)
-* [Better Related Posts](http://wordpress.org/extend/plugins/better-related/)
-
-Probably there are more, I'm afraid.
-
-== Changelog ==
-
-= 1.1 (2013-07-24) =
-* Fixed the manipulation of DROP INDEX query.
-* Removed desctructor() from shutdown_hook.
-* Enabled LOCATE() function in the query string.
-
-= 1.0 (2013-07-07) =
-First release version of the plugin.
-
-== Upgrade Notice ==
-
-When auto upgrading of SQLite Integration fails, Please try manual upgrade via FTP.
