Please can someone help before i pull all of my hair out, i have trawled these forums and gone through every suggestion to fix my worldpay module 2.12 in my zencart 1.5 version, i have followed the instructions, checked the passwords match, when you cancel a payment on world pay page it takes you to my website design in worldpay saying payment cancelled. but I still get a debug email from worldpay saying transaction status failure, when you proceed with a payment it doesn't return to my website just the world pay payment sucessful page and i get a callback failure email from worldpay, the order doesn't show in zencart and i get no information to say what has been ordered. i have installed worldpay about a month ago and zencart a couple of months ago, i know this has been a common problem but i don't know what else to try.
