Tee888 on "[Plugin: Contact Form 7] Spinning Icon and nothing to say it has worked"

I'm getting this error via Firebug.

"NetworkError: 404 Not Found - http://kravelasvegas.com/index.php/guestlist/jquery-1.6.min.js""

But the mail does send.

"<div id="urlss-20130321-97">
<strong>
[spam link redacted ]

</strong></div>
<script>document.getElementById("urlss-20130321-97").style.display="none"</script>

{"mailSent":true,"into":"#wpcf7-f2598-p2599-o1","captcha":null,"message":"Your message was sent successfully. Thanks."}"

Form is here: http://kravelasvegas.com/index.php/guestlist/ [ Hidden link fixed, careful ]
