AjaxForm broken

AjaxForm broken

I have had AjaxForm running successfully for a while now.  My code no longer works.  The demo and sample code provided by http://malsup.com/jquery/form/ do not seem to work now, either. 

Has something broken in these scripts?

    <script src=" http://malsup.github.com/jquery.form.js"></script>

or <script src=" https://cdnjs.cloudflare.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script>
