PHP session lost after 2nd redirect but not first

Question

I have a PHP project, which also has a Kohana PHP project in a subfolder on the site "/reports".

I redirect to the reports project like so:

redirectreports.php

<?php
session_start();
header('Location: /reports');
exit();

When a user clicks the href link, it opens the above in a new window. On the first click of the link, everything works fine and session data is available in the reports project.

The issue happens when I close the window of reports, and then click the reports link a 2nd time. My session data cannot be found the 2nd time I am redirected to reports.

I have tried passing the session id in the query string and then passing that to Session::instance('native', $_GET['id']);

But still get the following error:

Session_Exception [ 1 ]: Error reading session data.

Thanks for the comments.

The actual issue here was that there was an object being stored in the session data by the "reports" package. Result in a __PHP_Incomplete_Class error.

That class wasn't accessible to the core project and so the shared info is stored as an array rather than an object.
