Where can I find the fix for this. I am getting this error: "USPS Error returned: Error Desc: API Authorization failure. RateV3 is not a valid API name for this protocol." So I am assuming it hasn't been fixed yet. Or alternatively, how can I fix this myself?
Thanks in advance!

You are receiving the error because you are using the USPS testing URL (http://testing.shippingapis.com/ShippingAPITest.dll) instead of the product URL (http://production.shippingapis.com/ShippingAPI.dll).
Set the URL to production (http://production.shippingapis.com/ShippingAPI.dll) in Administration > Configuration > Shipping > Shipping Rate Computation > USPS (US Postal Service), "Edit" > Configuration (tab). Also, for a new USPS account, you need to submit a request to the USPS Internet Customer Care Center to have your profile updated to production.
