My hoster is not able to help me. Neither does the debug mode.
It’s 3.9.2 running on PHP 8.1.16. I have the same setups on the same hoster multiple times and it works. I also have a local clone of the site which works fine. What I can say, the frontend is running fine, it’s just the panel. I can click the message away and then I see a half way loaded panel with partly emty fields. I compare the write-read-settings on the content and the blueprint folders with another project. No differences there.
What can I do?
