title: IE is telling me I have mixed SSL content when I don't
body: <p>In IE it is giving me the "some items on the page are not secure" message. I have tracked it down to this line:</p>
  
  <pre><code>&lt;script type="text/javascript" src="lightbox/js/prototype.js"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>which is a lightbox script I downloaded. I tried making the src relative or absolute with https it happens either way. And only in IE.</p>
  
  <p>Heres the page if you need to see it: <a href="https://www.kranichs.com/cart.php" rel="nofollow noreferrer">Clicky</a></p>
  
  <p>Thanks!</p>
