Magento Fatal ERROR on SERVER - A session is active.

[jeganee]

Hi,

I uploaded my Magento project files to the server. But getting below fatal error.

 A session is active. You cannot change the session module's ini settings at this time in /home/vln9w1ofdev8/public_html/vendor/magento/framework/Session/SessionManager.php on line 129";i:1;s:9436:"#0 [internal function]: Magento\Framework\App\ErrorHandler->handler(2, 'ini_set(): A se...', '/home/vln9w1ofd...', 129, Array)

Thanks,

KARTHIK

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');
}
