USPS Shipping Options Error(Oh No!)


Recommended Posts



I'm a newbie, and I've searched the boards for this problem and have found some helpful links. I think I've done everything right, but I'm still getting the "An error occured with the USPS shipping calculations" error.


Here's what I've done / checked:


1)Configuration Shipping/Packaging options has correct country,zip


2)Set up shipping API account with USPS - have userId/Pass and have had them move us to the production server.


3) Although it doesn't look necessary in the latest version, modified usps.php "shippingapitest.dll" per usps instructions ("shippingapi.dll).



I noticed that if I set a shipping zone in the usps preferences, usps doesn't show up at all, but would be happy at this point to get some help.
