 * Hi
 * I’ve built a custom plugin. I’m using the following to add a submenu.
 *     ```
       function menu_items() {
       	add_submenu_page('whatever','Whatever Admin', 'Whatever Admin', 'manage_options', 'whatever', 'whatever_admin');
       }
       ```
   
 * The function whatever_admin used to be called something else. I renamed the function
   and now when I click the link in admin – it’s still trying to find the old function
   though I can’t find any reference to it anywhere.
 * `call_user_func_array() expects parameter 1 to be a valid callback, function '
   old_function' not found or invalid function name`
 * How is this possible? and how can I resolve it?
 * Thanks in advance

 * Found reference to it. uncommented line which should have been commented.
    Ignore
   question.
 * Though I must say…Wordpress’s admin menus are very frustrating.
