Hi! As far as I know a warning about Undetermined languages should show up in a box in the Settings page, but instead the text "undetermined_language_warning" shows up. I think that's a bug.
Before lemmy.ml was down I remember the message correctly showing on my account on that instance.
I believe that's an issue with 17.2 that has been fixed in 17.3 (which we haven't upgraded to yet). Hopefully it will resolve when we upgrade
