No one can submit events now for my site. When you click submit it takes you to a blank page that says Are you sure you want to do this? with no buttons to push.
When I’m logged in it doesn’t do this and submits the event but that doesn’t do me any good if no one else can use it.
Could you go into ‘Settings->Permalinks’ and hit Save again? This will reset your permalinks and hopefully resolve the issue. Let me know if that helps!
