@Nullpo when trying to open a new repo that I created, I think I discovered an issue. The url is being cut off. If I had to guess you look for the last period in the repo to get the extension. Not sure about that just a guess.
Here is a screenshot of the issue.

The url showing in your textbox next to the refresh button is: https://github.com/johnhidey/johnhidey.githu and the actual url should be https://github.com/johnhidey/johnhidey.github.io
If you heed anything else from me please let me know.
