Change language

Hi =)

When i created a forum, i accidently chose english for the language. But i wanted in french !!
So, i went to "configuration" and i changed the default language to french. But it doesn't work.
What should i do ?
Im thinking to delete completly the forum but i don't know how to do it. I went to "configuration", but i couldn't find anything that can delete the forum.

You also need to change it in your profile.

Profile >> Preferences >> Look for Language
