title: Multiple post slide in on page with Slider revolution
body: <p>i'm using <strong>revolution Slider</strong> with visual composer in wordpress and i have an issue, i can't resolve.
  I try to add 2 post-based sliders in one page but it didn't work. My first slider just show the load spinner and my second one didn't show at all.
  This 2 sliders are based on a same template but they have 2 differents shortcodes.
  Here is the code of my page :</p>
  
  <pre><code>[vc_column el_class="sous-titre-site"]
  [rev_slider_vc alias="slider-actualite" title="Actualités" el_class="sous-titre-site"]
  [/vc_column][/vc_row]
  [vc_row css=".vc_custom_1484839039158{margin-top: 25px !important;margin-bottom: 25px !important;}"]
  [vc_column]
  [rev_slider_vc alias="agenda" title="Agenda" el_class="sous-titre-site"]
  [/vc_column][/vc_row]
  </code></pre>
  
  <p>I have nothing in my console too, no error or something...</p>
  
  <p>Thanks for help</p>
