   array or string given in /home/botffy57/public_html/scandilab.com/wp-content/
   plugins/if-menu/if-menu.php on line 110

 * I found out that
 *     ```
       add_filter('if_menu_conditions', 'exis_menu_conditions');
       function exis_menu_conditions($conditions) {
       	$conditions[] = [
       		'id' => 'user-validated',
       		'name' => __('If user is validated', 'exis'),
       		'condition' => function($items){
                           return true;
                       }
       	];
       	return $conditions;
       }
       ```
   
 * needs to become
 *     ```
       'condition' => 'callback_function'
       ```
   
 * you need to add function not to build it there
