Hint for solving Error 500 on Cyberpanel Admin Url (Port 8090)

I suddenly got error 500 if I try to call my cyberpanel admin Url (on port :8090)

But not on *:8090/phpmyadmin

Last thing I did a day before was a Ubuntu system update with:

apt dist-upgrade

Becaue I had a snapshot from before my system update, I experimented a bit and could fix this issue in my case by doing an cyberpanel Upgrade to the same version with the official way:

I belive my database (or something else) was updated and some cyberpanel specific settings got lost by this update.

So my advice; Do a “upgrade” of cyberpanel installation to the same version if you have the Error500 on admin panel url.
