I have an XML access key from UPS and have UPS as the only available shipping option.
When I go to checkout and put in a zip code it says “This shipping method is currently unavailable. If you would like to ship using this shipping method, please contact us.”
I think I have all of the fields filled in correctly. Is there a debug mode or anything else to help me figure out why it’s not working. I can’t tell if it’s a Magento or UPS problem.
