I am trying to figure out when a user comes to the site I have built using the royal theme and they try to register for an account is there an option where they can register an account through facebook login – http://8theme.com/demo/royal/register/? is this something possible?
Unfortunately, there is no such option. You may try to use some plugin or try to edit the file wp-content/themes/royal/framework/theme-functions.php (find the section “! Registration Form”).
If you need help with additional customization contact WP-Kraken team because it’s not included in our support.
