Error 410 gone after moving from local server to live

I have created a site and everything is working fine locally in WAMP, however, I moved everything to my shared hosting account and am getting a 410 error:

Gone
The requested resource
/admin/product_edit_parse.php
is no longer available on this server and there is no forwarding address. Please remove all references to this resource.

Additionally, a 410 Gone error was encountered while trying to use an ErrorDocument to handle the request.

I moved all files and everything else seems to be working so far except for this one file. This file is not actually viewable anywhere it is on the admin side of my site for editing products. My site sends a HTTP request to this page and gets a response via AJAX like so:

var xmlhttp = new XMLHttpRequest();
xmlhttp.onreadystatechange = function(){
    if(this.readyState == 4 && this.status == 200){
        console.log(this.responseText);
    }
};
xmlhttp.open("POST", query_string, true);
xmlhttp.send();

I can only see the 410 error in the console when nothing happens.

If I go directly to the pages URL with the query string attached (admin/product_edit_parse.php?foo=bar&bar=foo) it gives me the same error.

However, if I go to the URL with out the query string I get a time out error:

This site can’t be reached
************** took too long to respond.
Try:

//-------------------EDIT-------------------\

This is how I'm building my query string
