Basara,
I appreciate your reply. Today I've been working with my host provider to try to figure out why it isn't working. Because it is not working on my new AbanteCart site and on one of their host AbanteCart test websites it would suggest there is a problem with the USPS extension.
However, I also ran a test on the AbanteCart DEMO application from AbanteCart.com. And it works OK there.
So for now my feeling is that there is something wrong with the software provided from my host. I'm talking to them about that possibility.
I'm curious if there are other AbanteCart users who are successful using the USPS and PAYPAL configurations?
I would appreciate any feedback.
Thanks
Frank
