title: "Origin 'null' is therefore not allowed access." - but domain is the same (css)
body: <p>I'm getting an error trying to load a css file in JavaScript: <code>XMLHttpRequest cannot load https://complice.co/m/user.css?3239. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access.</code></p>
  
  <p>...but the domain I'm loading it from is the same! Why is it showing up as Origin: <code>null</code>? I'm just using a basic AngularJS <code>$http.get(url)</code> to fetch it.</p>
  
  <p>Also I'm pretty sure this has worked before, and I haven't changed anything. I also wouldn't be surprised if it just worked again next time. But what I'm wondering is <strong><em>how is it even possible for this error to occur?</em></strong></p>
