Properly setting up a feed

  1. Feed links have to use the category slug (not the name) (“Blog-Artikel” –> “blogpost” in the case of the site in question)

  2. Feed links have to conform with the localization of the page offering the feed (i.e. “category” –> “kategorie” for a WP site with a Germain domain. Funny enough, the WP site language of the site in question is set to “English”)
