Session or cookie not expiring?

Hi,

I have a problem with WordPress Social Login. Everything works fine with facebook login, but the moment you log out and try again, it gives me this error: https://ibb.co/ePw9xw

If I clear my browser cache and cookies, then it works again until next log out. Any ideas? I tried getting ‘Logout clear cookies’ plugin and also tried to use this code from here: https://silvermapleweb.com/using-the-php-session-in-wordpress/ add_action(‘init’, ‘myStartSession’, 1);
add_action(‘wp_logout’, ‘myEndSession’);
add_action(‘wp_login’, ‘myEndSession’);

function myStartSession() {
if(!session_id()) {
session_start();
}
}

function myEndSession() {
session_destroy ();
}

But that did not help, maybe because it is not wordpress social login specific.
