I get the following warning when I go to Admin>Modules>Shipping . The warning pops up on the top of the mod. I have read threads that were like 3 years old. And someone had a link for a fix, but the link no longer exists. I have also followed these instructions http://www.zen-cart.com/wiki/index.p...UPS_XML#STEP_4 Just can't get it setup. Can someone help?
