The page was completely blank, the checkout_process.php and the admin/server_info.php
Using plugnpay which is identical code to authorize.net except the url but that should not affect the admin/server_info.php.
I am curious if there is some issue with IIS6 in windows 2003 with the new securities that are built into it.
Thanks for the response.. I have logged probably 80 hours trying to fix this.
