Website does not render. Error 404

[Coral-Buddy]

Hello!

I am contacting you because I am trying to setup an online notebook using your Jekyll Now repository for building an online blog in GitHub.

Here are the steps I have performed.

I followed your instructions and made changes to the -config.ymil file on line 45
I changed the default.html on layouts to my github account information
I changed the README.md file to have my information
I changed the about.md file to have my information
I changed the repository url to my account and repository information.

I have reviewed the changes that I did and doublechecked any misspelling, but nothing seems to solve the issue. Do you have any insight on what try to troubleshoot it?

Thank you so much for creating this tool!
