 * Hi Ben,
 * i updated to version 0.7 and i’ve got the following error:
 * >  Strict Standards: call_user_func_array() expects parameter 1 to be a valid
   > callback, non-static method Expire_User_Admin_Help::admin_menu() should not
   > be called statically in /wp-includes/plugin.php on line 429
 * By the way, i see this message at **ALL** installed plugins on the plugin page!(
   [Screenshot](http://images.weber-nrw.de/2014/04/expire_users_bug.png))
 * You will see this message, when you enable the debugging mode in your config.
   php file:
 *     ```
       /**
        * For developers: WordPress debugging mode.
        *
        * Change this to true to enable the display of notices during development.
        * It is strongly recommended that plugin and theme developers use WP_DEBUG
        * in their development environments.
        */
       define('WP_DEBUG', true);
       ```
   
 * Can you have a look at this and fix it?
 * Thanks. Great plugin!

 * Please post a new issue if you still experience this problem.
