Any ideas why the menu manager isnt working? Thanks August 17, 2010 at 12:42 pm #32677 James MorrisonParticipant Hi! If files are missing from WordPress core this would cause problems. I recommend 1.) backing up your database 2.) using FTP, upload all the WordPress core files again Best regards, James Author Posts Viewing 2 posts - 1 through 2 (of 2 total) The topic ‘The database tables that are necessary to make “Menu Manager” work error’ is closed to new replies.
