I am still on test mode as I have a problem with WorldPay.
I have installed the WorldPay module and it sometimes works perfectly well, but sometimes the callback does not redirect the shopper to the check_out success page.
This means that my orders are not being displayed on admin and I do not know what was sold!
I ran tests from different computers, with different browsers, credit cards, etc. and the problem seems to be random.
Does anybody know the solution to this? I called WorldPay and was told that many people call them with this same problem but they cannot do anything about it ... so, I hope there is someone out there with the solution :) Please help!
