Feed(Aggre)gator takes a list of RSS feeds and creates a single list of RSS items from those feeds to be displayed as a widget. You can select how many items you want to display and whether you want to show the entries chronologically or you want to show the latest entries from each feed listed.
You can also opt to display the date associated with the RSS item as well as the author of the item.

This plugin disables all RSS/Atom/RDF feeds on your site. It is useful if you use WordPress purely as a content management system (and not for blogging). All requests for feeds will be redirected to the corresponding HTML content.
There are a couple of options to tweak the plugin’s behaviour – go to <code>Settings -> Reading</code> to see them.
If you come across any bugs or have suggestions, please use the plugin support forum. I can’t fix it if I don’t know it’s broken! Please check the <a href="https://wordpress.org/extend/plugins/disable-feeds/faq/" rel="ugc">FAQ</a> for common issues.
