Visit the [theme documentation](https://matcornic.github.io/hugo-learn-doc/basics/what-is-this-hugo-theme/) to see what is going on. It is actually built with this theme.
Check that your Hugo version is between `0.19` and `0.21` with `hugo version`.
> From `0.22`, Hugo team introduced a long awaited feature: [nested sections](https://github.com/gohugoio/hugo/issues/465). As Hugo team deleted some functions on which this theme was based on, **this theme fails with current Hugo version**. A complete rewrite is needed and is [currently under construction](https://github.com/matcornic/hugo-theme-learn/issues/51). Be aware that this new version will possibly make breaking changes.
> Until the v2 is not out yet, feel free to check [Docdock](https://github.com/vjeantet/hugo-theme-docdock), a great fork of hugo-learn-theme by [@vjeantet](https://github.com/vjeantet) that works and embraces latest features of Hugo!
