I tried to translate ttrss to korean (ko-KR) but I noticed it already has translationed mo/po file in locale/ko_KR folder, but somewhy I can’t selece korean form language setting in preference, nor autodetect can detect it.
it there a file or something in database to force-change language setting.
looks like you’ll need to add the language to the list at include/functions.php line 80 (get_translations).
