CyberSource + Canadian Payment! Anyone got similar problems?

Hi people. I use CyberSource (pathetic choice being a Bank of America customer), and had problems with Canadian payments. I updated CS.php according to this post: http://www.zen-cart.com/forum/showthread.php?t=37726
However, some people seem to still report unable to process payments. After hitting Part 3 Submit Payment button, it connects to the CyberSource blank page, then loops back to Part 1.
Anybody know what is going on?

jack911:
You do not provide much info to diagnose the problem but it seems to be related to the CyberSource server displaying a blank “hosted order page” to the customer.
If the blank page is displayed to Canadian customers only, then I have no suggestions without further investigation. Should all customers be affected, then I would verify the hosted page that you have defined on the CyberSource Business Center >> Settings >> HOP Settings >> Appearance >> Order Page.
Over all, my suggestion is to use the SOP (Silent Order POST) connection method instead of the HOP (Hosted Order Page) connection method. I seriously tried to get the HOP method to work but without success. Please see post: http://www.zen-cart.com/forum/showthread.php?t=49297

Hope this info will help,
