Error when redirect using the popup version

Hi!

Some of my users are having some trouble loggin in with WSL. I’m using the popup version, that opens a popup window when the user select a social media to login. They said that, when they click on a social media option, the popup opens, the message telling that the plugin is connecting to te provider is showed, then they visualize a blank page inside the popup, and the redirect that would happen when they successfully are logged in, never hapens.

I did some investigation on my php erros log, and checked some errors:

PHP Catchable fatal error:  Object of class WP_Error could not be
converted to string in (...)/wp-content/plugins/wordpress-social-
login/includes/services/wsl.user.data.php on line 85

in a php_errorlog in the root of my wp install…

CSRF state token does not match one provided.

…and …

PHP Fatal error:  Uncaught exception 'Exception' with message 'No provider ID specified.' in (...)/wp-content/plugins/wordpress-social-login/hybridauth/Hybrid/Provider_Adapter.php:55
Stack trace:

  thrown in (...)/wp-content/plugins/wordpress-social-login/hybridauth/Hybrid/Provider_Adapter.php on line 55

… both errors in a php_errorlog located inside this folder: wp-content/plugins/wordpress-social-login/hybridauth.

Maybe these errors are related to this issue? Anyone have a suggestion?

Thanks for any help!
