Problems with rotation in the Facebook (old) module
Facebook is currently upgrading Facebook accounts to the new Facebook design. This conversion takes place without requiring any action on the part of the user and independently of whether the user logs in with a user name and password or uses an existing (cookie-based) login.
This can lead to problems when harvesting data in the Facebook (old) module if the rotation function is used. Accounts (alongside the primary account) that are incorporated in the rotation are no longer used by SNH if an unidentified conversion took place.
Temporarily incorporate every rotation account as a primary account once and reverse the design conversion.
Alternative: Use the Facebook (new) module.
