jquery.mmenu not working with exact same demo code

Question

http://mmenu.frebsite.nl/

1. Local version of the menu works
2. Doesn't work when uploaded onto my server. However, the demo version it comes with still works...

Error it gives is Uncaught TypeError: undefined is not a function for the .mmenu() function

<script type="text/javascript">
            $(function() {
                $('nav#menu').mmenu();
            });
</script>

The function is defined, however, in

<link type="text/css" rel="stylesheet" href="jQuery.mmenu-master/src/css/jquery.mmenu.all.css" />

AND jquery is also attached

any thoughts?

Answer 1

use the java-scripts and css hosted on their website rather than one in the example also it seems you need to decorate the element with the following class mm-current
