Same issue as well! And worst, when I tried to save a page in French, I got an error 404 page not found… On update go to http://dev.fredericsune.com/wp-admin/post.php instead of ?post=xxxx&action=edit&lang=fr. I tried to rebuilt the permalink structure, don’t translate fields – translate group fields, everything I can imagine of and still, error 404 and unable to save.
