I enabled visibility of the widgets only to the homepage – however, alternative pages still show up with this:
Primary Sidebar Widget Area
This is the Primary Sidebar Widget Area if you are using a two or three column site layout option.
By default it will load Search and Archives widgets as shown below. You can add widget to this area by visiting your Widgets Panel which will replace default widgets.

Widgetized Sidebar
This panel is active and ready for you to add some widgets via the WP Admin
Is there a way to disable the sidebar on other pages altogether, rather than just the widgets?
