I have a similar issue to McKay Christensen's post on the UPS shipping module not working after the upgrade from 1.0 to 1.1.
I tried aravot's solution of making sure the only options selected are:
UPS ACCESS CODE
UPS USER ID
UPS PASSWORD
Ship from zip code
'Ship from zip code' is a text field, and I wasn't sure to have it blank or put in a different entry. Currently I have "Override_Source_Zip" placed in this field.
What do I need to change?
