Hi,
I imported language (in my case Bosnian). And I changed in the preference tab for administrator. After that something crazy happened. I get the picture below. Anything I click doesn't do anything. And I cannot change the lanugage back because admin is only user on my server that can change language for others. Now my admin is stuck like this.

I am hereby asking you to tell me where this is setting written for a user. Like what table in PostgreSQL database?
The only way to change it back to English is to manually change it in database (i see no other way).
