Just add, when Program is set to No, menus also disappear.
Is this system only designed for a close community? Thanks.

More confused now as when I try to disable “Program” for logged in user, the widgets still displays correctly.

Found it’s probably related to this: Navigation panel doesn't load
But not exactly know why, have to open XWiki page to unregistered user, and will expose all user profiles which I don’t want, thinking of a workaround to it.

Temporary work around : set XWiki (page and children) to be visible, but (page) to be invisible, it won’t show in the tree, however, clicking creator/modifier of the page still can lead to user profile, I’ll just delete information from users I guess.
