Here's a showstopper bug that just surfaced on a DNN 6.1.3 / SmithCart 4.86.0 - pressing "Calculate Shipping" throws an error, and then prevents viewing the cart until site Cache is reset. It also appears to clear the cart of it's contents.

We're doing USPS rate reurn for Priority Mail and Express Mail. We'd like to also do First Class, but it doesn't help that there is also ANOTHER showstopping bug ("First Class" bad behavior) mentioned in another thread over here (http://www.smith-consulting.com/Forum...).

Any workarounds? Any patch? FRUSTRATED.
