title: Getting mixed-content errors even though I’m only using https URLs
body: <p>I'm having the SSL warning messages all over my website after switching to SSL for several assets:</p>
  
  <blockquote>
    <p>Mixed Content: The page at '<a href="https://example.com" rel="nofollow noreferrer">https://example.com</a>' was loaded over HTTPS,
    but requested an insecure script '<a href="http://example.com/script.js" rel="nofollow noreferrer">http://example.com/script.js</a>'. This
    request has been blocked; the content must be served over HTTPS.</p>
  </blockquote>
  
  <ul>
  <li>I checked the page source, every single script/css is requested over https.</li>
  <li>I even checked the dynamically created html by using the code inspector.</li>
  <li>I disabled Javascript in case a script was loading these assets dynamically.</li>
  </ul>
  
  <p>None of these things showed a single http:// request. I'm out of ideas to try and find what is causing this. Any ideas or suggestions?</p>
