Validation errors – Octopage - Blogging with Jekyll, Markdown and GitHub pages Review

This app is beautiful and easy to use, but it doesn't let me sync new posts to my github repo. When I try it throws a validation error. Would rate higher, but that's what the app is designed to do. Without that functionality it's not useful.
