I installed the new version of OSC edited the USPS file, input the user name and password but I think the imbedded link is wrong, I get the following error on the checkout page:
United States Postal Service
An error occured with the USPS shipping calculations.
If you prefer to use USPS as your shipping method, please contact the store owner
I checked my user name and password at the USPS site and no issue there logging in.
In the edit area it shows;
You will need to have registered an account with USPS at http://www.uspsprioritymail.com/et_regcert.html to use this module.
Click on that and it is a redirect to; http://www.usps.com/webtools/
Anyone know what might be the problem?
