Script blocked due to mime type mismatch
<p>It was reported to me this morning that one our marketo landing pages was not displaying properly in IE. When I checked the page none of the css or js was loading, so it's pretty much an empty page with a few images. </p>

<p><a href="http://pages.vistex.com/MIDEM_Music_Ally.html" rel="noreferrer">Link to landing page</a></p>

<p>Using dev tools in IE I noticed the error: </p>

<pre><code>SEC7112: Script from http://pages.vistex.com/js/forms2/polyfills/placeholder/placeholder.css was blocked due to mime type mismatch
</code></pre>

<p>I'm using IE9 the browser seems to go into IE 9 Compatibility View with IE7 Standards. We do have a group policy forcing compatibility view on our domain on our network. </p>

<p>Could this just be an internal network error? Or is this error firing for all users. I was able to check the page in IE11 off our network and it looks fine. </p>
