Hi,My company just bought the Pro version and, as a 1st step, we try to see how the Javascript -> SideNav can be customized. When following the provided tutorial (https://mdbootstrap.com/javascript/sidenav/) we get a consistent error: index.html:23 Uncaught TypeError: $(...).sideNav is not a function     at index.html:2 Testing Environment: ================== Browser: Chrome Code (stripped) ------------------------     <link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet">     <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/font-awesome/4.4.0/css/font-awesome.min.css">     <link href="css/bootstrap.min.css" rel="stylesheet">     <link href="css/mdb.css" rel="stylesheet">     <link href="css/style.css" rel="stylesheet">     <script type="text/javascript" src="js/jquery-3.2.1.min.js" ></script>     <script type="text/javascript" src="js/popper.min.js"></script>     <script type="text/javascript" src="js/bootstrap.min.js"></script>     <script type="text/javascript\" src="js/mdb.min.js"></script>     <script>             // Initialize collapse button              $(".button-collapse").sideNav();              // Initialize collapsible (uncomment the line below if you use the dropdown variation)              $('.collapsible').collapsible();             // SideNav Options             $('.button-collapse').sideNav({                                             edge: 'right', // Choose the horizontal origin                                             closeOnClick: true // Closes side-nav on <a> clicks, useful for Angular/Meteor                                           });             // Show sideNav             $('.button-collapse').sideNav('show');             // Hide sideNav             $('.button-collapse').sideNav('hide');     </script>
