 * Hi,
 * I installed and succesfully verified the Facebook provider.
    When I use the login
   button, a popup shows up for a moment, and then the browser navigates to [https://troovix.com/wp-login.php?loginSocial=facebook](https://troovix.com/wp-login.php?loginSocial=facebook)
   and the title in the browser shows “Error en la identifiacion” (Error identifying).
   Then I am redirected [https://troovix.com/wp-login.php](https://troovix.com/wp-login.php),
   not being able to login with Facebook.
 * On my computer I am logged out my facebook account.
 * How can I get the identification to work?
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Ferror-identifying%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Hi [@aklibaba77](https://wordpress.org/support/users/aklibaba77/)
 * I checked the social login on the linked page and as I see the problem is related
   to your WordPress membership setting.
 * Currently when I try to connect with the Facebook social button, it displays 
   the following error:
    “No se permite el registro de nuevos usuarios.”
 * By default Nextend Social Login inherits the WordPress membership settings from
   WordPress side bar > Settings > General > Membership – Membership Anyone can 
   register. Since you have this option disabled, the registration will also be 
   disabled with social login.
 * **How to fix it:**
    If you would like to enable the registration with Nextend
   Social Login, regardless of your WordPress settings, then you should go to Nextend
   Social Login > Global Settings > General tab > Membership and change it to Enabled

 * Let me know if you would still see the problem after that!
 * Best regards,
    Laszlo.

 * Hi I followed these instructions:
    Nextend Social Login > Global Settings > General
   tab > Membership -> enable.
 * I am still getting the same behaviour. After using facebook login the page starts
   reloading, for a moment shows title in tab “Error en la identifiación”, then 
   redirects to standard wordpress login page.
 * I had the same settings on my test environment (troovix.alexmoloni.com) and everything
   worked fine.
 * Waiting to hear from you

 * Hi [@aklibaba77](https://wordpress.org/support/users/aklibaba77/)
 * I checked your site again, and this time both the registration and the login 
   worked fine with my test Facebook account.
 * Could you check please if this problem also occurs with:
    -another Facebook account
   that, is not registered on your WordPress site, yet? -another provider like Google
   or Twitter?
 * If the problem only happens with that Facebook account exclusively, then is it
   possible you used multiple Facebook Apps with Nextend Social Login? Since Facebook
   doesn’t provide the real user id of the user, but instead an App Scoped User 
   Id, which differs in each Facebook App.
    This means that the same Facebook account
   have different User ID in App1 than in App2. When you link a social account to
   a WordPress account, this user ID is stored as a link. So if you registered an
   account with App1 but later you reconfigured Nextend Social Login with the credentials
   of App2. Then the stored user ID won’t match with the user ID that App2 provides,
   meaning that you won’t be able to login to that account.
 * If the problem is actually related to this, then you will need to either:
    -change
   back to your previous App -or Unlink the Facebook account from your WordPress
   account. Unlink buttons are displayed only for the logged in users, and only 
   if you use the shortcode with the unlink parameter: [https://nextendweb.com/nextend-social-login-docs/theme-developer/#shortcode](https://nextendweb.com/nextend-social-login-docs/theme-developer/#shortcode)

 * Great thanks. Indeed I had a nother Facebook App created for the test site. I
   unlinked the facebook accounts using the unlink button (I used this code to generate
   it: “echo NextendSocialLogin::renderLinkAndUnlinkButtons();”.
 * After unlinking, the facebook login started working fine again.
 * Thank you very much for your help

 * Hi [@aklibaba77](https://wordpress.org/support/users/aklibaba77/)
 * Thanks for letting us know that the problem was actually related to a previous
   Facebook App.
 * I am glad the unlink-ing method fixed the problem!
