Hello,
Ever since we upgraded to the latest version of SP Page Builder and updated to Joomla 4.1.0 we have noticed that anyone in any group below Superuser (such as Administrator or Manager) is unable to login to the backend. It gives them an HTTP Error 500 internal server error. We were successfully able to reproduce this issue and fix it on our test server by removing SP Page Builder. We need SP Page Builder functional on our production server and cannot remove it. Please advise.
Joomla 4.1.0, SP Page Builder 3.8.6
Thanks!
