Duplicate Session IDs? !
I realize that while testing I'm using the same browser on the same day, but I have added session destroy and setcookie behaviors to the SUCCESS pages, however, I am seeing that in spite of that, eCart is putting in duplicate OrderReferenceID's based upon the session ID of the eCart: a3783893b8761d5110a107a043d4801a is used for 2 transactions made hours apart....
Here is the code at the bottom of the success pages:
<?php if (session_id != "" || isset($_COOKIE[session_name()])); session_destroy(); ?>
