On the page in question, I called the 'logout' function and redirected to that page: [logout.php] <?php session_start(); ob_start(); session_destroy(); header("location: http://your_site.back_to_page_that_is not_logged in.php"); ?> Note that I used an absolute url -- it seems to make a difference. [Btw, I note that you use double quotes for $_SESSION['orderinfo'] -- just wondering . . . . HTh, Andre
