PHP session is working on localhost but not on actual server

Question

i'm having trouble to pass session variable to another page. It is working on localhost but not on server. I would want to pass $_SESSION['user_check'] to editpasswordsignup.php but whenever i click submit, $_SESSION['user_check'] is empty.

This is loginsignup.php

<?php

include('db.php');

session_start(); 

?>

As you said it's working on localhost and not on the particular server, you might have a different settings in php.ini. Check out http://php.net/manual/en/session.configuration.php
