Built a complex form, tested, and everything worked. Today, the form shows up as an entry in WP Admin but when I preview it or try to edit it or view it in a page on the front end, none of the forms settings / fields show up ( "Oops, form not found" on front end, blank form on back end ). Checked the database, the form has all of the meta data still intact.
Any known causes for this sort of behavior ( to narrow our debugging )?
