Re: Magento Fatal ERROR on SERVER - A session is active.

I solved this issue by editing the below file

 

/vendor/magento/framework/Session/SessionManager.php

/vendor/magento/framework/Session/SessionManager.php
// Enable session.use_only_cookies
if (!$this->isSessionExists()) {
    // Enable session.use_only_cookies
    ini_set('session.use_only_cookies', '1');
}
