Broken Navigation Links

[alex-xsp]

When moving through the pages like this:

1. https://docs.blissroms.org/
2. (Clicking on Setting Up Environment) - https://docs.blissroms.org/getting-started/installations/
3. (Clicking on Introduction) - https://docs.blissroms.org/getting-started/installations/getting-started/introduction/

The browser shows me an 404.

I noticed this behaviour happens also with different paths but not always.

I am using Firefox (verified in private mode with extensions disabled) 142.0.1 (Snap Ubuntu)
