That is what I did the first time. It is set to TEXT. I removed the USPS methods. I re-installed. I still dont get the options to turn on and turn off under intl. They are always turned on. After I edit the settings, I can see all of the intl options, but when editing the settings, there are no check boxes or text for me to change.
Is this driven by the USPS site, or in the DB? I find nothing in the DB and am wondering if driven by USPS, maybe my id does not have access to intl? Any other thoughts? I really think I have done exactly as you state and still nothing.
