500/404 error after finishing the installation wizard

[errotu]

Hi!

I try to install Antragsgrün on my uberspace (following this guide). Unfortunately, after I finish the installation wizard, I first receive a 500 and then only 404 errors when accessing the website.

As this might be a specific issue with the uberspace hosting service, I've also reported the issue here (Uberspace/lab#1127 (comment)).

Do you have any ideas how to fix this?

Thanks a lot for all your help!

Hi! If it's a 500-error, then there should be a file runtime/logs/app.log, that has the exception log at the end of the file. If you can either post it here, or, if it contains non-public information, send it to tobias@hoessl.eu? Maybe that gives an indication on what went wrong...

Thanks for your help! Here's a redacted version of the log file (removing the domain and the local user name, nothing more).

Also, I tested some of the older versions. I was able to successfully install v4.9.1 (but no newer version) and to upgrade to v4.12.0 step-by-step via the internal web updater (important: I had to execute the database migration after every single update, not only once after all the file updates are completed).
