title: str_get_html doesn't work and return blank
body: <p>I got a blank screen after I run below code</p>
  
  <pre><code>&lt;?php include('simple_html_dom.php');
  $html = getSslPage('https://www.reddit.com/r/nottheonion/comments/3aev89/kim_jongun_claims_to_have_cured_aids_ebola_and/');
  
  
  function getSslPage($url) {
      $ch = curl_init();
      curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
      curl_setopt($ch, CURLOPT_HEADER, false);
      curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
      curl_setopt($ch, CURLOPT_URL, $url);
      curl_setopt($ch, CURLOPT_REFERER, $url);
      curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
      $result = curl_exec($ch);
      curl_close($ch);
      return $result;
  }
  
  $html = str_get_html($html);
  
  echo $html;
  </code></pre>
  
  <p>the hardest part of debugging it is it work sometime with other url. I wonder why coz the pages have the same DOM structure. Anyone have idea why is it happening? </p>
