Hello — when navigating to the page site/home it redirects to the main page (site), while the main page lists site/home as its canonical URL. I also found other problems with deleted pages: for example, if the Albums module is removed (possibly the same happens with other modules), the page content is removed but the page still returns a 200 response code, which is incorrect. Ideally UNA CMS needs some kind of model/interface to view and sort all pages so they can be managed — checked, and garbage pages removed. There are many such pages, but you only notice them when search engine services start reporting them.
