USPS Shipping Issue in Powerstore 3
We have established the account with USPS Web Tools and received our username and password. We have also contacted them and had them activate our account (switch it from test mode to production mode). We have obtained the production URLs from them and plugged them into the Shipping Settings in Powerstore, but we are still getting an error when trying to test purchase.
We only have PayPal Express Checkout enabled at this time.
When trying to purchase, we are redirected to PayPal directly from the cart (before any shipping options are presented or an order summary is presented). We log into PayPal and then see an order summary and total without shipping, and then click continue, at which time we are redirected back to Powerstore and the order is canceled due to an error.
In test mode with no shipping options enabled, the cart performs fine.
What are we missing or doing wrong? Any help is appreciated.
