title: Original page not working after custom page deleted in Github Pages
body: <p>I added a custom page to a website I was hosting on Github Pages. But, it didn't work, so I removed it by blanking the custom domain name in Settings. However, when I tried the original page, it still redirects to the custom page, which does not work.</p>
  <p>I originally thought caching was the problem, but it still persists after 10 minutes.</p>
  <p>What's happening, and how do I fix it?</p>
