Does this happen every time you try to fetch posts? With every group?

Seems to be only on a group I'm admin of: id 26106060048

Great project btw :)

Sometimes FB returns this evil answer. It destroys most implementations

{ "error": { "message": "An unknown error has occurred.", "type": "OAuthException", "code": 1, "fbtrace_id": "q9JAVCCyyxT" } }

These fields seems safe to use: ?fields=from,to,message,created_time,updated_time,likes,comments

The others often create unknown errors.
