 * Sorry for not understanding this. I keep getting this error:
 * Warning: call_user_func() expects parameter 1 to be a valid callback, no array
   or string given
 * Apparently it is because $item is undefined. Below is the sample on the plugin
   page:
    But what is $item supposed to be ????
 * ———————————–
    function my_new_menu_conditions($conditions) { $conditions[] = 
   array( ‘id’ => ‘single-my-custom-post-type’, ‘name’ => __(‘Single my-custom-post-
   type’, ‘i18n-domain’), ‘condition’ => function($item) { return is_singular(‘my-
   custom-post-type’); } );
 *  return $conditions;
    } ———————————————————
