I've got a problem that I think is due to a cookie stored on my box somewhere as a result of a failed transaction.
Worldpay processes the transaction and sends its confirmation emails.
The call back url http://<wpdisplay item="MC_callback"> produces the WP box at the top of the page and the header beneath it.
The rest of the page won't load and the sale is not confirmed/logged by OSC.
WP does not send a failure email and there are no warningmessages.
Although I go through the WP process. The goods are still in my cart.
Can anyone help and shed light on what I'm missing.
