title: Wordpress admin not loading css/js
body: <p>I'm having a problem with the admin on a Wordpress site. I've scoured the interwebs and seen lots of other people with the same problem, but no definite solution. The admin is showing like this:</p>
  
  <p><img src="https://i.stack.imgur.com/nHK6X.jpg" alt="enter image description here"></p>
  
  <p>And when I inspect it, I get a <em>500 (Internal Server Error)</em> on both <em>load-styles.php</em> and <em>load-scripts.php</em></p>
  
  <p>Anyone know what's up, and how to rectify?</p>
