I have a local GitLab server in my company, which I installed in a Proxmox VE 5.1 container, I installed the server under Debian 9.3 (Stretch).
The issue is that when I try to change the default language (English) to Spanish in the configuration of the user profile, it says that it does it correctly, however it never translates.
I think I can do it through some configuration file by changing the default language What is this file, or what should I do?
PS: I made the installation manually using the installation script on the official GitLab website.
