I have used Jekyll to generate my personal github website.
Here’s the source:https://github.com/itumel/itumel.github.io
The live demo is at: http://abeginnersguidetohackathons.com
The problem I am having is that although index.html works just fine. author/Sharon/index.html is not found. The same applies for tags. They cause 404.html to be displayed. What could be the problem?
