Hello,
Of course I found out at the last minute that the old version of the USPS API was turning off today (which broke USPS for me) and I scrambled today to get this fixed. I'm running a 2.2 store ( http://fuelinjectionent.com/webstore ).
I got the new module discussed here, followed the instructions and when I go to check out, I get a blank white page. If I turn off USPS in the admin tool, everything works again (except I only get United Parcel Service of course).
I've backed out of this twice and restored it to the original state...then tried it again. Same result each time. At least I'm consistent.
I skipped the jQuery thing in the instructions because A. I don't know how to do it and B. It says it won't work for 2.2 stores anyway. Could this be related? I turned off showing the international options and that didn't help.
Help! My store is very dependent on USPS. Anyone have ideas what I've done wrong or what I'm forgetting?
Thanks,
Spud
