I keep on getting this after the shipping, <sup>&reg;</sup> It will be like mediamail<sup>&reg;</sup>($2.42) or whatever the shipping method is, how do I remove the <sup>&reg;</sup> ?
are you just getting that with the USPS module? (the error code you gave looks like a USPS problem, try disabling that shipping method and see if you still get that error).
It's mentioned in several other sites that the garble you mentioned above is from the usps api version not working right with the api version you are using.
Using 1.90 version and it's only on the USPS shipping. I looked on several other sites that are using nopCommerce and they aren't getting that string, I was just wondering if there's a way to remove the nonsense from that
