Since yesterday 11th of April 2006, my UPS module doesn't work anymore. It has been working for 2 years now.
I already installed the new UPS(XML) version and I still get the same error. Everytime a customer goes to the checkout page, I get an error page that checkout_shipping.php doesn't exist.
If I disable UPS(XML) the checkout page works again. Now I can only offer USPS to my customers.
I also checked the UPS rate access key, username and password. Asked a new UPS rate access key and it still doesn't work.
Does anyone know what's wrong here? I didn't change a thing and suddenly it doesn't work anymore.
Is there something changed with the link to the ups-site?
