After upgrading Wordpress to 5.8 and CiviCRM to 5.39.0, the event registration page does not work.
This is the url:
These are the symptoms:
- the h1 of the page is "CiviCRM"
- the body of the page is "Do not delete this page. Page content is generated by CiviCRM."
- the title tag in the header contains the title of the event
- no profile fields, hence no possibility to register for the event.
- no errors in ConfigAndLog
- several cache clear had no effect
What could be the cause of this error? What can I do to debug this further?
