I currently move the documentation of LinkAce from Jekyll to Hugo and got problems with the content structure, and it’s driving me crazy. The whole source of the site is available on Github.
The content structure is the following:
content/
└─ docs/
├─ index.md
└─ v1/
├─ general/
│ └─ about.md
├─ ...
└─ index.md
The index.md pages in docs/ and v1/ are content pages.
Based on this structure and the Hugo documentation there is nothing wrong about this structure and I couldn’t find any information about issues with particular nesting levels.
I assume that based on the structure, the about page in the general folder should get the URL /docs/v1/general/about.
However, Hugo does not render any pages in the v1 directory at all. Only the index page in the docs/ directory is showing up. I tried so many things, deleting the index.md files from the parent directories, renaming the pages, manually set an URL in the front matter. But nothing works. 
Can anybody help me?
The website is live and available on Netlify: https://linkace-website.netlify.app
As you can see, the sitemap is basically empty: https://linkace-website.netlify.app/sitemap.xml
