I just noticed that in Atahualpa Theme Options if I mark a given sidebar to appear on Single Posts and "Page" pages, it also shows up when somebody goes to a page or post id that doesn't exist. I thought the "Not Found" option would be in play in those cases.
Is there any way to make it so that the sidebar does not show up on those error pages? I'm trying to hide the sidebar from people who are not logged in. Right now if somebody is smart enough to know the standard URL structure they can see the sidebar w/o logging in.
Thanks
