I have a Magento store that has been converted to a "one deal at a time" type store, and the checkout process is broken. I've been trying to debug this, but have hit a wall, primarily due to my limited understanding of Magento.
On the saveOrder step, when clicking "Place Order", the page shows "submitting order information, then the message clears and the shopper is still on the Order Review page.
I've analyzed with Firebug and HttpFox, and I can see the order information is being sent

My problem seemed similar to this post: http://fishpig.co.uk/magento-tutorials/magento-checkout-error-undefined-javascript-alert
but I'm not getting an "Undefined" alert, so I added the "else" statement below:
nextStep: function(transport){
if (transport && transport.responseText) {
alert(transport.responseText);
try{
response = eval('(' + transport.responseText + ')');
}
catch (e) {
response = {};
}
if (response.redirect) {
location.href = response.redirect;
return;
}
if (response.success) {
this.isSuccess = true;
window.location=this.successUrl;
}
else{
var msg = response.error_messages;
if (typeof(msg)=='object') {
msg = msg.join("
");
}
alert(msg);
}
if (response.update_section) {
$('checkout-'+response.update_section.name+'-load').update(response.update_section.html);
response.update_section.html.evalScripts();
}
if (response.goto_section) {
checkout.gotoSection(response.goto_section);
checkout.reloadProgressBlock();
}
} else {
alert('transport.responseText');
}
},
I am getting the JS alert with no text, so it looks like transport.reponseText is empty. The main references to empty response text I've found appear to be related to same-origin policy, which I don't think applies, because my AJAX post is to and from www.domainname.com.
When I call the saveOrder function directly in the browser, I'm receiving a valid response:
https://www.domainname.com/checkout/onepage/saveOrder {"success":false,"error":true,"error_messages":"Credit card number mismatch with credit card type"}
and HTTPFox shows I'm getting a 200 response from the Ajax call, but the responsetext is simply empty. I find no PHP errors or errors in Magento's exceptions log. The only thing I'm finding that might be related is "Headers already sent' in Magento's system log:

Does anyone have any suggestions why else the responseText is coming back empty?
