For some reason, shipping is no longer working in my store. Today I deleted some Rule Sets, but I don't believe any were used in shipping. I've even created a new test product, set its weight, and set it to ship with enabled services. USPS is enabled, as are several USPS methods. No funky rules. The warehouse address has been unchanged.

Just getting no Shipping options when I get to that part in the checkout.

We have very few items in the store that actually have a shipping fee, so the last one that worked was in December 2011. I'm not sure if it then stopped working, or if it was the rule set deletions I did today. Can't see how they would affect the new test product anyhow.

Any ideas?
