Today, when I woke up to continue my work, my site was in french !

So, after some tests, I discovered that language preference seems to be saved into the cookie. You have to clear your cookie to see the new default language (or wait for the cookie to be marked as invalid).

Hope this will help.
Great advice, this worked for me!

Thanks!
