call_user_func_array() expects parameter 1 to be a valid callback

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)

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!
