I recently installed Moodle 2.5 and have begun to create a course with activities in/for French. I would like to have the interface be in French, but I haven't gotten that to happen. I have downloaded the French language pack and manually installed it. It appears in the as English (fr) rather than Français. English (en) and English (fr) appear on the language menu. It doesn't matter what I select, the interface is always in English. On my colleague's older version moodle site, the languages appear as English and Français.
I've looked at the FAQ and have unchecked the autodetect language from browser option. I don't know what to try next. All my course content is in French. Should I have set the language before creating any content? Any direction you can give would be appreciated. For now, I'll live with it like it is.
