Can anyone help as im hitting a brick wall with configuring Protx (SagePay) using eCart.
Ive spent an absolute fortune with Webassist having bought practically every extension they do and all technical support did was a 1 line reply referring me to the debugging eCart transactions pdf which left me a bit disappointed with them.
Ive followed the guide to "Using Protx as your eCart Payment Gateway (PDF)" exactly and all it is doing is sending me to the checkout_failure page instead of the VSP Server page.
When i debug it, it says VPSProtocol=2.23 Status=INVALID StatusDetail=The data in the BillingSurname field you supplied is an invalid length. Max is 20 characters. The guide says you can leave this blank and even if I fill it in, it still returns the same error message.
Can anyone advise where im going wrong.?
Any help will be greatly received and appreciated.
