title: jQuery Uncaught TypeError with Theme Punch Revolution Slider
body: <p>I'm having a problem that I can't track down. I'm using the <a href="http://themes.themepunch.com/?theme=revolution_jq" rel="nofollow noreferrer">Revolution Slider</a> and I keep on getting jQuery errors:</p>
  
  <pre><code> ▼ Uncaught TypeError: Cannot read property 'length' of undefined (repeated 86 times)
  
      p.extend.each                            jquery-1.8.2.min.js:2  
      a.fn.cssAnimationRemove     jquery.themepunch.plugins.min.js:18  
      (anonymous function)        jquery.themepunch.plugins.min.js:18  
  </code></pre>
  
  <p>The problem is on <a href="http://coolcoops.com/home" rel="nofollow noreferrer">this page</a> and I believe it's causing the weird problem where the picture doesn't fully disappear when the slides change. It leaves the picture there, and then it suddenly disappears. Like this:</p>
  
  <p><img src="https://i.stack.imgur.com/CqZyc.png" alt=""></p>
  
  <p>It's given me nothing but trouble and I can't seem to track it down. Any suggestions?</p>
