viewing source of the checkout page shows the following error:
<b>Fatal error</b>: Call to undefined function mhash() in <b>/home/jbarracks/public_html/testing/WA_eCart/checkoutScripts/WA_simlib.php</b> on line <b>30</b><br />
this means that the go daddy server does not have the mhash library enabled.
i fixed the error by ending line 30 of the WA_eCart/checkoutScripts/WA_simlib.php file:
return (bin2hex (mhash(MHASH_MD5, $data, $key)));
to:
return (bin2hex (hash(MHASH_MD5, $data, $key)));
