So I\'m following this guide here to create a Github page
I created a repository, cloned it to my project directory and pushed, finally got to this last step:
I had the same problem. I think first you need to check out if YOUR Github Pages have been enabled. This you can check out from "setting". Then change whatever html web site from"github.com/username/repo1/repo2/repo3.../blob/master/file.html"
to "username.github.io/repo1/repo2/repo3.../file.html" .
Then have a try. Good luck.
