When you change the permalink structure then this is a problem for bookmarks of users and also for search engines to link to your posts. This plugin uses the slug of the new url and search for a ID in the database of WordPress. If it finds a post according to the slug, the Plugin will redirect to the correct post and send a header message “moved permanently 301” to change the url on the index of search engines.

Change Permalink Helper

Awesome!

It checks the Permalink and redirects to the new URL, if it doesn't exist. It sends the header message "moved permanently 301"
