Hello,
I am (or would like to be) a new user.
I installed the vikunja 0.24.5 .deb package on Debian 12.8 (no docker) and kept getting “internal server error” while it logs “ERROR 
18b unknown time zone ”
This first occurs when creating a user. The user is created though.
Creating a project works fine, also adding a task seems to go well. But when I reload or change to a different view which should show open tasks or tasks due, I get the error and no task is displayed.
A look into the database reveals that the tasks have been created, though.
But Field “timezone” in table “users” In the database contains “”.
So it does not seem to be correctly populated at start (or config.yml is not parsed correctly?)
Everythings seems to work fine after manually entering my timezone into the database field.
Another thing that does not seem to be read from config.yml is logging:
Even though the logfile path is set to /opt/vikunja/logs it does log to syslog. I had to add
StandardOutput=append:/opt/vikunja/logs/vikunja.log
StandardError=append:/opt/vikunja/logs/vikunja.log
to /usr/lib/systemd/system/vikunja.service (or to an override file).
Kind regards
Oliver
Welcome! 
That should show an error during startup.
Can you share your config?
Hmmm, still not quite familiar with this forum software… it appears not to allow text attachments.
Here is a diff of my config and the one I extracted from the .deb archive (config.yml-orig):
