Facebook API 2.0 issue has been resolved.

We have great news.

After two weeks of making everyone crazy Facebook backed down on app review requirement. You no longer need to submit your app for review.

Everything (well almost everything) went back to way it was before Apr 30, 2014

The only new requirement from now on is that the facebook App, Facebook profile or page and the user who authorizes the app MUST belong to the same Facebook account.

Please see the Update #7 here for the complete story: http://www.nextscripts.com/known-issues/facebook-issues/

SNAP for WordPress version 3.3.7 is compatible with new requirements. Please update if you have earlier version.

This issue is now closed.

PS: if you still experience the problem, just create a new app and make sure that Facebook App, Facebook profile or page and the user who authorizes the app belong to the same Facebook account
