worldpay problem
Hi, I installed ecart today, and have the cart and shop working fine. But, when I have gone through checkout, and click checkout on the confirm.php page, I am getting the following error from worldpay:
Sorry, there was an error in processing this transaction:
The information sent from the merchant's site is invalid or incomplete. Please send the following information to the merchant:
The transaction cannot be processed due to one or more of the following:
* the installation ID field is blank or contains invalid characters
* a different submission protocol is required. For instance, a more secure submission may be required
* the installation number is invalid
Server information 05/Jul/2010 16:30:37 Server ID mg4imsps4p (WPReq-1670203)
ps- I am not a code-monkey, but a photoshop head!
Please help.
