Facebook can be disconnected from dlvr.it for three main reasons:
1. If you change your password on Facebook, all applications which are granted Offline Access (the ability to post when you aren't actively accessing the site in a browser) have that permission revoked.
2. You have revoked the authorizations granted to dlvr.it.
3. You haven't properly authorized dlvr.it to post to your Facebook groups. For more information about this connection, visit our support document on how to properly connect groups.
To resolve either of these issues, simply reconnect your account with Facebook.
You can also set up alerts so that dlvr.it will notify you if we have lost Facebook authorization.
