Me again. Still researching my issue. I am going back through my old shopping cart and looking for any coding with USPS to try to determine where my issue is. But I just got this debug email from my website. Please note that I am using the most recent download. Here is the actual info from the Developers Tool Kit:
Line #14 : * @version $Id: usps.php 2014-10-30 ajeh Version K6 $

So here is the debug message I got:
<?xml version="1.0" encoding="UTF-8"?>
<Error><Number>80040B1A</Number><Description>API Disabled: RateV3. The RateV3 API is no longer available. Please follow the "RateV3 to RateV4" transition guide in the announcements section at www.usps.com/webtools to migrate to the latest version or contact your software provider or shipping administrator for assistance.</Description><Source>USPSCOM:oAuth</Source></Error>

Will start doing my research now to see if I can find my fix. Appreciate any help.
