Since you've pointed your domain back to the EB-powered version
of the website, we're unable to see the issue so it's a bit difficult to
troubleshoot. With that said, here are some tips we typically give
regarding the Event Detail Page (EDP) for those utilizing the HOTK option.
1) The page title must be Event
2) The permalink must be /e/
3) The page must be using the [eb_event_details] shortcode
4) The page role must be set to Event Details
I've attached a screenshot of what a typical EDP page looks like in the wp-admin.
Hope that helps!
