I'm getting the " UspsCom:oAuth" Failure on the shipping page.

Hi; Eric

When I signed up USPS sent me this email.

Congratulations on completing your testing using the U.S. Postal
Service's Web Tools Application Program Interfaces (APIs). Your
profile has been updated to allow you access to the Production Servers.

The URLs you will use for the Production Servers are:
ShippingAPI.dll
ShippingAPI.dll

So I used ShippingAPI.dll.
I did notice the API part was in caps, I tryed both ways ShippingAPI.dll & Shippingapi.dll
and got same responce.

This is what my USPS globels looks like.

// USPS Shipping Settings
$WAGLOBAL_USPS_User = "***********"; // get this when you sign up for API access
$WAGLOBAL_USPS_Server = "http://production.shippingapis.com/ShippingAPI.dll"; // change this to the live server when you go live
$WAGLOBAL_USPS_ShipType = "FIRST CLASS"; //Enter the appropriate value for domestic shipping, based on the USPS Shipping key at the bottom of this page.
$WAGLOBAL_USPS_IntShipType = "Economy (Surface) Parcel Post"; //Enter the appropriate value for shipping to international customers, based on the USPS

I'm at a loss....

Thanks Eric

Ron
