Hello,
I just installed this contribution and I have a problem. When I click to USPS Label Shipping buttom, it goes to USPS page with all information from my order and that is great, but when I click on Continue button I am getting this message
Error 404: Servlet Not Found: com.usps.shipping.domestic.servlets.ShipmentPrepServlet
I have an account with USPS.
Can anyone help me with this problem?
Thanks
