Where is the KB Preference Files in Detail?

Too bizarre - now, just a few moments later, on the same two different computers everything worked fine on just a few moments ago, Grim’s url, mine in the OP, and putting “Preferences” in the KB search engine is routed to … the same generic page that prompted my OP again … it’s like the target page has changed in the last few moments, and twice in the last few hours? (Sorry for the non-techy language).
