title: Toggle menu error
body: <p>I am getting this error when the site goes to mobile and I try and open up the nav menu</p>
  
  <p>ReferenceError: e is not defined

  <pre><code>    &lt;script&gt;
  $(document).ready(function() {
  
      $('#menu-toggle').click(function () {
        $('#menu').toggleClass('open');
