I have an application to manage a users Facebook notifications, the app requests offline_access as well as manage notifications permissions. My logs have been filling up with Facebook errors, I understand that the change password error is going to happen, but what I don’t understand is why I am getting these errors:
Facebook Error: Error validating access token: Session has expired at unix time 1320012000. The current unix time is 1320191317.
Facebook Error: (#200) The “manage_notifications” permission is required in order to query the user’s notifications.
They are occurring way too often to be users just rejecting the permissions and the access tokens that are expiring have expirations of 0
For future reference, offline_access has been removed, now it is possible to get an access_token with a life span of 2 months
