My new Github page isn't showing up
I'm not sure if the site just needed some time to show up, but I was getting a 404 error after pushing my master branch... Then I changed my 'theme' in the repo's settings. All of a sudden it started working! A file called config.yml appeared with the theme metadata.
Try to push an empty commit and refresh the page. It should work.
git commit --allow-empty -m "Trigger rebuild"
git push
