AA,
When you 'enabled all of them', you mean every setting you saw, or just anything with OAuth in the name? Sorry to be a bit slow on this, I just really want to make sure I understand what you needed to do. We are planning to update the docs over the next week to accommodate the recent changes from Facebook.. it's always a cat and mouse game trying to stay 100% updated though.
Glad to hear you got things going though, sorry for the confusion, and should you need anything else, just let me know.
Thanks,
Alex
