## 説明

WordPress データベースをデフォルトにリセットします。すべてのカスタマイズおよびコンテンツ
を削除します。ファイルは変更せず、データベースのみをリセットします。

プラグインやテーマ開発者にとって、とても便利なプラグインです。

If the admin user exists and has level_10 permissions it will be recreated with 
its current password and email address. If the admin user does not exist or is a
dummy account without admin permissions the username that is logged in will be recreated
with its email address and current password. The blog name is also kept.

The plugin will add an entry to the Admin Bar under the site title and has the ability
to reactivate itself and other plugins after the reset.

**Database Compatibility:** This plugin supports both MySQL/MariaDB and SQLite databases.
For SQLite installations, the reset process will delete the database file and redirect
you to the WordPress installation screen.

### アップグレード

 1. Use the plugin updater in WordPress or…
 2. Delete the previous `wordpress-reset` folder from the `/wp-content/plugins/` directory
 3. Upload the new `wordpress-reset` folder to the `/wp-content/plugins/` directory

### 使い方

 1. Visit the WordPress Reset Tools page by either clicking the link in the Admin Bar
    or Tools>WordPress Reset
 2. Type ‘reset’ in the text field and click reset.

## インストール

 1. Upload the `wordpress-reset` folder to the `/wp-content/plugins/` directory or 
    install directly through the plugin installer.
 2. Activate the plugin through the ‘Plugins’ menu in WordPress or by using the link
    provided by the plugin installer

## FAQ

### How can I get this plugin to automatically reactive after the reset?

Add `define( 'REACTIVATE_WP_RESET', true );` to `wp-config.php` above `/* That's
all, stop editing! Happy blogging. */`

### Can this plugin reactivate other plugins automatically after performing the reset?

Add an array called `$reactivate_wp_reset_additional` to the global scope by placing
it in `wp-config.php` above `/* That's all, stop editing! Happy blogging. */` that
contains the plugin basenames of the plugins to activate, such as:

    ```
    $reactivate_wp_reset_additional = array(
        'hello.php',
        'akismet/akismet.php'
    );
    ```

### Does this plugin work with SQLite databases?

Yes! For SQLite databases, the plugin will delete the database file and redirect
you to the WordPress installation screen. This means you’ll need to set up WordPress
from scratch after the reset, unlike MySQL/MariaDB installations where your admin
user is automatically recreated.

Well, it works… but if the wordpress database has a diferent prefix it also deletes
wp_users. In my case was w7_users and deleted all users. I guess it works fine if
the prefix is default wp_users
