The update of the WordPress-SEO plugins has resulted in extra content being added to a blog site’s RSS feeds.

The extra content is “The post xxx originally appeared in yyy”.

To remove this content, you will need to log onto your blog site and from the wp-admin page, go to SEO -> RSS.

Remove the text in the ‘Content to put after each post’ edit section.

Save the ‘Save Changes’ and you should be good to go.
