I can't get the internationalisation/language setting at kk:wikipedia to work properly.
Every time I change&save the preference (I tried English, Dansk, and Deutsch), and then visit a random article, it displays the interface messages in the wiki's default language, and displays this popout message from the ULS sidebar/toolbox: "English дегеннен тіл өзгертілді"
If I then visit the preferences page again, it displays a popout message saying "Language changed from қазақша".
It seems to work properly at other wikis.
Version: unspecified
