Sorry, I already put this in the wrong place. I'll start it again as a new topic....
I've just installed UPS XML. Everything seemed ok at first. I installed it in the admin/modules/shipping area, entered UPS username etc etc.
However, when I attempt a test purchase it goes horribly wrong! I added things to cart and then when I click on checkout I get an HTTP 500 error on the checkout_shipping.php page.
I've double checked everything that people seem to usually do when HTTP 500 errors are presented (i.e. file/folder permissions and making sure the php files are uploaded in the proper mode) and I can't seem to fix it.
Has anyone else had this issue upon install of UPS XML?
Thanks.
