‘Only Pages in Feed’ is a little plugin that modifies WordPress RSS feed to exclude all ‘Post’ types and show only ‘Pages’ in it. So if you are using WordPress as a CMS and want only Pages to appear in your site feed, this plugin is for you.
The plugin needs no configuration. Just activate it, and you are good to go. Deactivating the plugin restores RSS feeds to their default state.
