Codeigniter 3 Session not working With PHP 7.1.4
I have an application built with Codeigniter 3 HMVC .The application was working fine on PHP 5.6 version, But after upgrading my PHP version to 7.1.4 I was not able to log in into my application. After a complete checkup I found that session is not setting at all. I role back to PHP 5.6 and session was working fine again while switching to PHP 7.1.4 bring the "session not working" issue back. I tried altering some config value like cookie prefix and cookie save name etc, nothing seems to fix it. Can anyone please help. A1ft I found that the issue is with some earlier version of Codeigniter 3
