About a week ago my USPS Shipping Calculator stopped working...sometimes.
For certain states it doesn't work/calculate (Indiana, Virginia, Maryland) but other states work/calculate just fine (Florida, California). Nothing has changed that I know of in in the past week or so that would disallow it to work.
Since it can't calculate, shoppers from those non-functional state can't checkout and order anything. I appreciate any help that can be offered.
