If you have the "Enable Automatic Registration" option set to 'Yes', after the user authenticates with Google, their account should be automatically created and authenticated on your site. If that's not happening, it usually means one of the following:
* The user doesn't have an email address in Google+ that is able to be imported. In this case, JFBConnect will send the user to our Login / Register page to at least provide their email address.
* The user already has an account on your site with the same email address as their Google+ email address. In this case, if you don't have the "Automatically link users by email" setting is "No", then the user will have to enter a new email or use the Login portion of the Login / Register page to sign in to their existing account.
If that doesn't help, please let us know what page the user is brought to after they try to login with Google. Also, if you've setup other social networks, please let us know if those are properly automatically registering users and logging them in.
Thanks,
Alex
