 * Hi,
 * after installation of **All-in-One Event Calendar** i get the following error
   accessing the admin panel:
 * `Fatal error: Call to undefined function get_current_screen() in C:\root\wp-content\
   plugins\frontend-uploader\frontend-uploader.php on line 185`
 * I figuered out that you have to include the screen.php file from the wp-admin
   directory like this:
 *     ```
       ....
       require_once FU_ROOT . '/lib/php/class-html-helper.php';
       require_once FU_ROOT . '/lib/php/settings-api/class.settings-api.php';
       require_once FU_ROOT . '/lib/php/functions.php';
       require_once FU_ROOT . '/lib/php/frontend-uploader-settings.php';
       require_once( FU_ROOT . '../../../../wp-admin/includes/screen.php' );
       ```
   
 * Is this a general problem of frontend uploader?!
 * Best regards
