UPS as only shipping method & error_shipping on checkout

Hi -

I've read a bunch of posts and am still getting an error_shipping error when checking out.

The only shipping method is UPS, and that's all that's enabled. The OpenCart version is 1.4.9.5, which is an upgrade from 1.4.8. I did the upgrade just now, hoping the error_shipping problem would magically go away.

This is my first use of OpenCart. I'm sure I've goofed up something.

The link to the cart is http://dev.farmersroastedsoynuts.com/shop/

I set up the shipping Geo Zone for USA, which is the only country being shipped to.

What have I missed?

Thanks,
Beth

"error_shipping" just means you haven't updated your language file from v1.4.6
The actual message says "No shipping options available"

The reasons are here:

Thanks!

What I discovered was that I only had one UPS method selected. Once I added more, I could check out successfully.
