I know there can't be a full troubleshoot right now, but the form found on the contest entry for a Facebook Page I manage (https://www.facebook.com/leisurepro?sk=app_277059139025204) was working with AJAX right up until the moment the contest went live. The form submits fine, but doesn't show any confirmation (or error) messages. I have to disable AJAX to slow the flood of emails I'm getting asking if their entries went through. I've tried the obvious refreshing/disabling cache, deactivating/reactivating gravity forms plugins. Like I said, it worked while testing it live on the Facebook Page earlier today, then I scheduled the form to kick in at midnight and now it's not doing confirmation/error messages.
