Hi there
After migrating to Joomla 5, I can no longer log in to the backend. The login screen appears, but when I try to log in, I get an error 500: Oops, something went wrong. I activated debug mode via configuration.php and set the error level to maximum. Unfortunately, I don't really understand the error report. I have already looked through various forum posts and it could have something to do with the SP Page Builder. However, since I can't access the backend, I can't uninstall and reinstall it. Can you please help me with this?
Thank you.
Dominik
