‘Pages and Posts in Feed’ is a simple plugin that modifies WordPress RSS feed to include both ‘Page’ and ‘Post’ types in the site’s feed. This creates a site feed with both pages and blog posts in it. Useful for those who use WordPress as a CMS.
The plugin needs no configuration. Just activate it, and you are good to go. Deactivating the plugin restores RSS feeds to their default state.
