It really sounds like you need to trouble shoot your ajax page. I would suggest entering the ajax page directly in the URL and see what's it's response is while monitoring the response body using the F12 (or similar) developer's feature of your browser
http://yourserver/yourpage.php, what comes back? Is it in valid json format, etc.
