We'll create fresh WordPress site with Pages and Posts in Feed installed. You have 20 minutes to test the plugin after that site we'll be deleted.
‘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.
