I just cloned your site and did some tests:
- I recommend using lowercase for folder and file names. I don’t know what the Hugo team recommends on this, but this makes it so much easier to manage files and permalinks. So, change
legalContent
tolegalcontent
in all the areas it occurs. - You have not defined any permalinks in your config.toml, so Hugo picks your directory and files names as the URL (e.g. example.com/legalcontent/impressum/)
