PHP Fatal error: Call to a member function authenticate() on null in /wp-content/plugins/yith-woocommerce-social-login/includes/class-yith-social-login.php on line 156

Answer 1

I had the same problem. I solve it by changing these lines:

\\wp-content\\plugins\\yith-woocommerce-social-login\\includes\\hybridauth\\Hybrid\\Providers\\Facebook.php: 27

public $scope = ['email'];

and

\\wp-content\\plugins\\yith-woocommerce-social-login\\includes\\hybridauth\\Hybrid\\Providers\\Facebook.php: 85

$accessToken = $helper->getAccessToken("https://[your-domain]/wp-content/plugins/yith-woocommerce-social-login/includes/hybridauth/?hauth_done=Facebook");

And

https://[your-domain]/wp-content/plugins/yith-woocommerce-social-login/includes/hybridauth/?hauth_done=Facebook must be registered in Valid OAuth Redirect URIs in FB administration
