I had the same problem and my solution was what I wrote before

Make a new po file in poedit and mo file, upload the to your buddypress and theme language maps

Check your General settings that you still have Danish as your language

Clear all cache and refresh site

You can also try to translate with Loco translate plugin and see if it makes any difference

I am also using KLEO Sweet Date, even if your theme language files are there, they are probably without translation.

When I opened my language file in poedit all my translation was gone and had to do the translation all over again and upload, then it worked

So open your po. language files and see if your translation is still there

I dont what theme you use but i found the solution for my problem

The latest update from my theme erased the theme language files which made that the byddypress translation didnt show, I had to translate my theme language file all over again and upload po and mo file and now buddypress is showing again.

Check if you theme language files are still there

Tried to deactivate Loco Translate but no change

Strange thing is that the registration form show my kanguage when logged in but if you are not logged it shows english in the register form

Is it possible for you to take a look if I send you the login details
