It worked fine for awhile however now it does not. WHen I try to manually put in the information into the graph api (https://graph.facebook.com/(id)//threads?access_token=(token)) I get this error:

{ "error": { "type": "OAuthException", "message": "(#298) You must be a developer of the application" } }

Any ideas on how to fix this issue? My app is not banned and i have verified my developer account.
