payment processing error in checkout - COD addon

[lightx]

hey everybody,

i encounter a problem with placing a order in my site.

when i submit the purchase form with all the necessary details and payment with cashondelivery option, i get a error saying: payment processing error.

after the error is showing, the site redirects to this link: https://sadeflowers.nethost.co.il/index.php?controller=order?step=1.

also i am using a module for checkout called: supercheckout by knowband.

site for example (its in Hebrew): https://sadeflowers.nethost.co.il/module/supercheckout/supercheckout
