    If I try to login with Facebook but deny the access to the email (the first time) I get the error:

    Undefined index: email in $site_url/wp-content/plugins/nextend-facebook-connect/providers/facebook/facebook.php on line 209

    It leads to more errors:

    PHP Warning: Cannot modify header information – headers already sent by (output started at $site_url/wp-content/plugins/nextend-facebook-connect/providers/facebook/facebook.php:209) in $site_url/wp-includes/pluggable.php on line 920

    If I delete the generated user from WP admin and try again, I am not presented with the Facebook registration modal box any more. Clearing the cache doesn’t help. I just get that errors but the registration is successful. I am testing with two facebook users, one always shows that errors the other one doesn’t.

    Hi @lubomir3000!

    Once you authorized the app, until your are logged in with your Facebook account ( at the official site of Facebook ) the modal will skip the login process and automatically authenticate you.
    Please note that the permissions you granted for the app, are stored by Facebook, what you can check at Facebook>Settings>Apps and websites>Active apps and websites

    So for testing purposes I would suggest removing the access for the App from there, otherwise you won’t see the modal where you authorize the app. Then you need to logout from Facebook and delete your user from your site.

    About your warning messages:
    We will probably need some additional information, so please get in touch with us directly at: https://nextendweb.com/contact-us/nextend-social-login-support/
    and refer to this topic.
