I am using Zen Cart 1.3.9d and I am having trouble with the payment module.

I am using Sage (Not SagePay) payment module. When the credit card is entered correctly, everything is ok. When I put in a bad credit card number, the page is blank and the URL of that blank page is:

9zxs.com/hnstore/index.php?main_page=checkout_payment&payment_error=net1&error=The+credit+card+nu mber+starting+with+1234+was+not+entered+correctly%2C+or+we+do+not+accept+that+ki nd+of+card.+Please+try+again+or+use+another+credit+card.&net1_cc_owner_firstname =&net1_cc_owner_lastname=&net1_cc_expires_month=01&net1_cc_expires_year=13&zenid =5084c7e95d12ff21864c4ce9702c333e

How do I fix it?

The Sage module is in the addon area:

"Sage Payment Solutins Moduel"
