When we put something in the shopping cart, then confirm the purchase, we get redirected to a payment page, either Moneris or Paypal. Since we are just doing test orders, we are cancelling them. Normally, we just get taken back to the site, however, we are getting a 404 error now.

without the actual 404 url unlikely anyone will be able to help...
