I did changed the facebook app (deleted the old one and generadet a new app). Every user who is using the facebook login get now the following message in their profile editing page
"There is an error retrieving your Facebook details. Facebook returns an error message of: "Error validating application. Application has been deleted."
and can not login with the new facebook app.
Can i solve the problem with clearing the table #__social_oauth table? as described in
http://stackideas.com/forums/there-is-an-error-retrieving-your-facebook-details
If yes, how und where can i do it?
regards,
Martin
