An Info Page is a Standalone Page that is linked directly from the Sitewide Navigation menu.

• In b2evolution v6, you could select a collection for Info Pages. All Standalone pages of that collection would become Info Pages.
• In b2evolution v7, which Standalone pages become Info Pages depends on the Site Skin you use. Check the settings of that site skin and check if it has a widget container for configuring the links you want as widgets.
