title: Flex Slider - animation not working
body: <p>Since upgrading from the Flexslider 1 to Flexslider 2 my animations aren't working (fade or otherwise).
  I'm getting no js errors, I've checked my doc type and the css all seems correct. It just doesn't seem to transition. Also when I navigate from one slide to the next via the navigation spots it stops auto-playing forever.
  Here is the js code I'm using:</p>
  
  <pre><code>$('.flexslider-desk').flexslider({
        animation: "fade",
        controlNav: true,  
        slideshow: true,
        slideshowSpeed:  7000,
        animationSpeed:  2000 ,
        directionNav:false,
        controlsContainer: $(".custom-controls-container")
    });
  </code></pre>
  
  <p>Any help greatly appreciated.</p>
