PayPal WPP Direct, GoDaddy

[hb_cmcl]

I've Googled and searched this forum, and seen a lot of references to the fact that GoDaddy makes you go through a proxy to use cURL, but I really seem to be missing something. I installed PayPal WPP (US) Direct Payments and PayPal Express Checkout (the official ones that came with the latest version of osCommerce, not a downloaded contribution) and after reading a bunch of these threads, I changed the "cURL Program Location" from usr/bin/curl to http://proxy.shr.secureserver.net:3128 in the admin area, but I am still getting hung up when I click "Confirm Order" and it tries to go to checkout_process.php. I don't get an error message of any kind, it just hangs for a long time and then gives up.

 

Is that not the right place to set the proxy settings? Is there something in the paypal_direct.php code that I need to change instead? I'm using the sandbox as the transaction server, and I've been trying to make test purchases using a fake name and the "4111111111111111" credit card with a fake expiration date and CVV2.
