Hi
I've just installed JFB Connect - so far so good. I've got the FB App set up and the login module configred and working. First login via Facebook works fine, but if I log out (Joomla) and then try to log in via Facebook again, nothing happens. I've tried various combinations of settings and currently have auto login of FB users and logout of Joomla only both set to No. Login with Joomla is fine. Account creation is set to Full Joomla user.
Caroline,
This can sometimes happen with new apps as the information is transferred to different Facebook servers around the world. It does generally clear itself up, as you've seen, but if you run into other issues, just let us know!
