I'm trying to using YouPlay Game Template. I have a problem with navbar toggle button.

When the button appear I make click and the menú not appear, no javascript error on console, nothing happens ...

You can see an example here: http://secgame.cloudapp.net

This is the code of my navbar:

<!-- Navbar -->
<nav class="navbar-youplay navbar navbar-default navbar-fixed-top ">
    <div class="container">
        <div class="navbar-header">
            <button type="button" class="navbar-toggle collapsed" data-toggle="off-canvas" data-target="#navbar" aria-expanded="false"
            aria-controls="navbar">
                Toggle navigation
                
                
                
            </button>
            <a class="navbar-brand" href="/">
                <img src="assets/images/logo.png" alt="">
            </a>
        </div>
        <div id="navbar" class="navbar-collapse collapse">

Argh!

Sorry for that I thought had returned the code ... I have had a problem with my source code repository ... :(

Thank you.
