Since Higfather, the "admin" link from the menu continues visible also for non logged-in visitors. I had a similiar issue with the dokuwiki version bevore, where the "show page code" button continued to be visible for everybody. A click on the "show page code" button resulted in an error messages, since this funcion is disabled. This problem disappeared with hogfather, but now its the "admin" button. Clicking on it results in nothing. So, not really a problem, but not nice… How can I make it disappear (for visitors, but not for logged in users/admins) ?
