Hi Philip
You worked your magic before for me and now I am having another problem with a world pay set up.
I've installed your latest module - however I cannot get worldpay to return to the site - it does if I cancel the test tranaction but not after completing a successfull test.
I have the debug emails on and they are not showing any errors, orders are being recorded. I have checked the return url and the enable shopper response button is ticked ( as is payment response, enable recurring reponse, payment response password & md5 secret entered).
Basically the site goes through the ordering process and the customer is taken into Worldpay to make the payment. The problem occurs at the last stage within Worldpay when the customer should be returned to the web site and an error message is displayed
"Email Error: Could not instantiate mail function."
This error message is displayed on this page - https://secure-test.wp3.rbsworldpay.com/wcc/card (https://secure-test.wp3.rbsworldpay.com/wcc/card)
This is the callback which has been entered - http://<wpdisplay item="MC_callback"> and all the setting have been entered to the test section of the rbs world pay section.
Any ideas ?
