Hi there,
Im trying to setup a hikashop cart system to plugin to a worldpay test account. Using the admin backend form for the worldpay global payment system, i have input the correct admin code, merchant code, MAC secret and installation ID. The worldpay account itself is fine - i can login and configure both test settings and live settings and the settings in the account are the same as the settings i have input into the worlday global payment system in the backend of joomla. However, i am repetitively receiving an "ERROR -> Merchant code/password error." on the last webpage in the checkout process on my website, and i am not redirected to the worldpay payment page. I have checked and run this about 20 times already and it still isnt working. Any ideas on what i'm doing wrong here - has anyone else had this problem and if so how did you get around it?
