When I use:
<?php $*********_cart->ClearCart();
unset($_SESSION['OrderID']);
?>
at the very end of the order confirmation page, I get:
Warning: Cannot modify header information - headers already sent by (output started at /home/**********/public_html/***********/***************.php:69) in /home/**********/public_html/***********/WA_eCart/*********_cart_PHP.php on line 118
I guess I cant empty the cart before the cart is written to the page, so I have to put this code at the end of the page(?)
