The URL you posted in that other thread was http://www.kotapparel.com/curltest.php ...

but when I click that it redirects me to a cPanel login to FreeHostia.

Evidently you meant to say http://www.kotapparel.com/extras/curltest.php


What's alarming is that the message "29 Naahh.. it will not work!" doesn't come from Zen Cart or curltest.php at all. That's something freehostia has done.

You'll need to sort out your problems with your hosting company.
