Just installed CB Connect and was testing it out with FB and when I logged into FB, then went to the site www.urotoday.com, clicked login, then clicked the FB login button, everything seemed to work except we're getting this error once your returned to the home page.

Empty Password Not Allowed

OK, figured this one out. There was an auto-login plugin installed for automatically logging a user in once they registered. Disabling this fixed the issue.
