I am running Dreamweaver CS4 and eCart 5.0.1 on a Windows Vista machine. During the check out process everythings seems to be going fine until it trys to get a shipping rate from USPS. It then redirects me to the shipping_failure.php program with a message of "Shipping Quote Failed
UspsCom :: DoAuth "
Is there any way to troubleshoot and find out what is going wrong? I have attached in a zip file with the confirm.php, WA_eCart_USPS_PHP.php and screen shot of the eCart shipping values to show what is set up. Thanks for your help.
