Config recovery per cli?



I need a miracle… :wink:
I just successfully destroyed my cute debian server by disabling the login. Is there any way to roll back config by cli? Access via ssh is ok, just the web doesn’t show any login window.
Now wondering if there’s a config file or a db command to check/correct.
All I wanted to do is to disable registrations. ;(

Any hint appreciated, thanks for your ideas.

Just a test server, but a couple of hours in it anyway…
