Can't take the github introduction course

[glubberson]

It makes the repository in my account but I can’t actually start the course. I’ve tried deleting the repository and trying again but I still just get the same error message.

I got to step 2 of the GitHub Introduction Course: Turn on GitHub pages… Now when I try to “Resume” - I get a 404 error? Page Not Found?
Can’t get any further.
