Currently, for categories to be able to work there is the requirement that a page with the exact same name exists. This requirement is hardcoded and is used in the post page (to show a link towards the category page).

We should remove the requirement for an exact name match. We should implement it with smaller manual (and confusing) coupling:

Please investigate if and how it is possible to add a "page" field in the categories.

In any category that the admins want a page to be connected, they can just select one of the existing wordpress pages.

No "exact name match" requirement should exist.

The feature should be implemented in two stages:

a) In the first release, only create the page field inside categories. When it is rolled out, ask all admins of existing sites to assing pages to the categories they want

b) On the next release, remove the name matching and replace it with just the selection of "categories that have a page assigned to them".
