Thread:Support/Problem with language interface

I have a problem setting my language interface to Arabic, I have tried to change it in preferences though It says Arabic in "Internationalisation", the page is in French and everything else is. I also tried to change it from the Display Settings button in the top of the interface, It does change to Arabic but as soon as I try to load a different page than the main one it goes back to French anyone has a solution for this problem?
