I used WP-FB-Autoconnect plugin. It works well if any existing user logs in using FB credentials. But, it is not stopping unregistered users from logging in. Ideally, it should direct the unregistered users to the registration page for them to fill some profile fields. Is there any way I could stop unregistered users from logging in using WP-FB-Autoconnect plugin? and also to redirect the unregistered users to the registration page.? Please help.
Also, is there any better free plugin that handles registration and login effectively? I am looking for FB login/register functionality something similar to the one in Pinterest..
