I have fork the pool/lanyon theme for my github pages ( https://github.com/poole/lanyon )
My problem is with the sidebar.
To add a category in the sidebar, I created a new file .md with :
--- layout: page title: my category ---
And it’s ok, this category was added in the side bar.
But now, if I want to put some content inside, my file looks like :
--- layout: page title: my category --- # Hello world
And if I actualize the pages, still 404 error… do you have any idea why ?
