# Fatal error – Menus Page

 * Hey there,
 * I have some problems, if I wanna reach nav-menus.php (Admin Area -> Menus)
 * As long as **Groups** is active, my menus are not shown. If I disable **Groups**,
   everything seems to work properly without any error-message.
 * It seems that this is the only problem. In all other areas of our website **Groups**
   seems to work fine.
 * There are 2 error-messages created, if I try to reach menus-page. One in Chrome
   Console and one inside my PHP-Error-Log.
 * Chrome Console:
 *     ```
       GET http://our-domain/wp-admin/nav-menus.php?action=edit&menu=60 / 500 (Internal Server Error) --> nav-menus.php?action=edit&menu=60:1
   
       Uncaught ReferenceError: columns is not defined --> nav-menu.js?ver=4.1.1:555
       ```
   
 * PHP-Error-Log:
 *     ```
       PHP Catchable fatal error:  Object of class stdClass could not be converted to string in /path-to-wp-content/plugins/groups/lib/access/class-groups-post-access.php on line 397
       ```
   
 * Line 397:
 *     ```
       $result = wp_cache_get( self::CAN_READ_POST . '_' . $user_id . '_' . $post_id, self::CACHE_GROUP, false, $found );
   
       inside
   
       public static function user_can_read_post
       ```
   
 * I’m Admin with all caps and it isn’t a network. Any idea why this happens ?
 * Thank You and best regards
