500 Internal Server Error on startup

[themao]

Hi there, thanks for such a nice software!

I am having some problems right there at the start - I've installed it as a dev package (Ubuntu 24.04), configured management console with pw-file (simply put the password into the file with that name) and then set password=mypassword in the config. But I am getting the 500 error and in the logs I see this:

What could be the problem here? Do I need to put password into pw-file in some specific format maybe? I didn't find any specifics in the docs about it.

Can you try restarting the web server? I was able to reproduce your issue momentarily but when I restarted the web server after the config change, then the issue went away.
