We just migrated to a different web server and updated PHP to version 8.0. When we try to use the Frontpage Editor in Joomla we get the following error message:

Not Acceptable An appropriate representation of the requested resource could not be found on this server.

Additionally, a 406 Not Acceptable error was encountered while trying to use an ErrorDocument to handle the request.

We are on Joomla version 3.10.11
