I have tried several different ways to debug this. nothing seems to work.
If I disable shipping altogether the transaction goes through with no problems. When I activate UPS I get the shipping fail. I searched this on other threads and have tried the suggested fixes with no luck.
I downloaded the fixes from my updates. no luck.
I pasted the "full request" "full response" code suggested to another user but it does not return anything at all.
I have a test item in my store for $1. I have successfully completed a checkout without shipping but I need to get this fixed.
