title: "XMLHttpRequest cannot load file:///... Preflight response is not successful" error
body: <p>I'm building a website and the page loads a navbar and some other resources with Jquery .load() function (as seen in code below). </p>
  
  <pre><code>&lt;script&gt;
          $(function () {
              $("#navbar-placeholder").load("subpage_navbar.html");
          });
  &lt;/script&gt;
  </code></pre>
  
  <p>When viewing the .html files locally on my computer in safari 5 everything works fine, and it used to work fine in safari 11, but now when I try to open the file I get an error:</p>
  
  <p>XMLHttpRequest cannot load file:///... Preflight response is not successful</p>
  
  <p>Are there any preferences I need to change in safari for this to work like it used to? </p>
