The order of the css and js files needs to be corrected.
Currently, the order is incorrect on the website:
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<link rel="stylesheet" href="Content/menu/styles.CSS">
<script async="" src="//www.google-analytics.com/analytics.js"></script>
<script src="http://code.jquery.com/jquery-latest.min.js" type="text/javascript"></script>
<script>
// analytics code
</script>
<script src="Content/menu/script.js"></script>

Additionally, make sure to use absolute paths instead of relative ones to avoid 404 errors when using url rewrite. For more information, refer to: Difference between Relative path and absolute path in javascript
