Old message but I'll respond. We had a similar issue and it turns out it had to do with the tags on the master page. To fix it, our designer went in and tags he thought were not as relevant. Anyway, so he basically he did a new master page, and added in his changes one by one and then he'd check to see what broke it. I do know after reading on others fixes on the web, the same solution won't work for everyone, because master pages are set up differently. In the end, it did fix the issue. I asked him if he remember what tag placement broke it, and it was some time ago and can't remember. You've probably gotten it fixed by now, so hopefully this answer will help someone else out. Cheers!
