We have installed OsCommerce 2.2 MS 2 and WorldPay V4.0 - 1.8 today, and implement a client's WorldPay account. Everything works fine in 100 and 101 mode, even the Callback function. But when we turn to 0 mode, the Worldpay response:
We are pretty sure that the Worldpay account is already live, and all currency, authorisation mode are the same as the ones we used under 100 and 101. Is there any solution to this?
