I'm currently developing a Jekyll-powered site and the line permalink: /:path/
that's working in my Jekyll local server, is NOT working either through the Configuration (_config.yml) or in the YAML Front Matter for each page (file.md) in GitHub Pages. They become literally outputted as example.com/:path/ instead of example.com/dir-name/ .
I've tried permalink: "/:path/"
but still not working, some said that some permalink will not work in the Jekyll version of GitHub. Upon researching, GitHub Pages have a Jekyll version of 2.4.0, that can be found in its "Dependency versions" page. There's also no mention of this in the GitHub Pages documentation in the Jekyll website.
Anybody know the exact list of the working Jekyll permalinks in GitHub Pages, so I can choose what permalinks to use in my project and for the future readers?
