title: owl-carousel not working in responsive mode
body: <p>I have an installation of owl on a site - works perfectly in desktop mode, but in mobile mode, the slides seems to disappear completely. </p>
  
  <p>My site is at: ypt.co.il (the 4 blocks below the large main slider - looks first in dekstop mode).</p>
  
  <p>This is the plugin code:</p>
  
  <pre><code>    $('.owl-carousel').owlCarousel({
          loop:true,
          margin:27,
          nav:true,
          responsive:{
              0:{
                  items:1
              },
              600:{
                  items:3
              },
              992:{
                  items:4
              }
          }
      });
  </code></pre>
  
  <p>Any input appreciated!</p>
