If you are using Login, then the Wayfinder snippet must be called uncached. The menu has to be generated differently for logged-in users to show the pages they can access, and you don't want that menu cached so that anonymous users see those pages in the menu.Thanks. I work at a test site, so there's no Login (at least, so far). But I'll remember your advice. Besides, I'll test what S.Zahn advised.
