Kevin,
For Facebook, when I try to login, the popup message changes to:
Error
This app is in sandbox mode. Edit the app configuration at developers.facebook.com/apps to make the app publicly visible.
You'll need to go into your [
developers.facebook.com/apps]App configuration[/url] and disable the Sandbox mode setting. That should take care of your Facebook issues.
As for the redirection, check a few things:
* Make sure the JFBConnect configuration for New User Redirection and Returning User Redirection are correct.
* Even if they look right, try changing them to a different URL and see if that changes the behavior.
* Check your User and System plugins to see if there are any that 'do' something after a user registers. Some plugins try to hijack the registration path/redirection and we can't do anything about that.
I hope that helps get you started,
Alex
