Breadcrumb links and structure on live wiki are broken

[line-o]

[edit] Initially, I followed an old or wrong link from a search result.
I learned admin.exist-db.org is deprecated, you should use exist-db.org/exist/apps/wiki instead.

Nevertheless the structure of the HowTos is unclear and the breadcrumbs are a little broken.

Clicking on HowTos Bla leads to a page with no further links. A list of child-pages would make sense here.

On one I happen to know of, XQuery3, the breadcrumb navigation and its links are broken.

Clicking on Switch Expression will just reload the page.

This is still the case. Also, this page's formatting is a bit broken.

Moreover, theare are subpages (which can access with searches, not sure if they're linked somewhere), see this for instance*.

*I cannot find that page's source in the repository here. The last link on that page (KeyTool IUI) is dead.
