The app is broken – Octopage - Blogging with Jekyll, Markdown and GitHub pages Review

It has problems choosing the repository link. For example my blog is at 403penguin.github.io but when I choose that repository it does this. 403penguin.github.io/403penguin.github.io I will change my review once this gets fixed.
