It seems to be when we are on any page from the devel instance (below the main menu page of that instance).
The getting started for example also shows this.

Paths are hardcoded with relative values so depending on the depth, it won't work [1] [2].

@vlorentz Maybe we could use absolute path like /sysadm/ or /devel/ instead?

oh yes, definitely. No idea why I made them relative

probably because that's what makes sense when you build locally the docs or something.

Pushed a fix and triggered a deployment of the docs.
Hopefully, this will fix it.
