Page not showing the theme after fix?

Hi,

My github page at xMikee1.github.io shows the theme for the index page, but not for the page ascii.md. I tried adding a few lines of code to the top (specified in https://github.community/t5/Pages/Page-not-showing-the-theme/m-p/5545#M393), but now there is a 404 message (when the file is clearly in the repository). Can anyone help? Thanks in advance.

EDIT: Issue fixed itself. Thanks!
