Hi Mark, imho this behavior makes sense, as you turn debug to 0 if your app goes into production (something tells me, that you don't want to show the home page as your entry page). The home.ctp which is displayed by the pages controller lives in
./cake/libs/view/pages/home.ctp
of your installation. But if you are in production you want to display the static pages from the
./app/views/pages
directory, which is the task of the pages controller. This directory is empty in a fresh cake installation.
Kind regards, Benjamin.
