Fatal error: Call to undefined function quiz_type_access_load() Getting the following error after switching servers. The setup is multisite on a linux box. The troublemaker is on subdomain. 
So far: 
disabled quiz and quiz submodules, 
cleared the cache, nothing really works.

Fatal error: Call to undefined function quiz_type_access_load() in /path/to/drupal/includes/menu.inc on line 411
Try to find and delete records in "menu_links" and "menu_router" tables of your database which have "quiz_type_access_load" occurrences.
