WordPress RSS feed not working? You are in the right place! RSS feeds allow users to subscribe to your blog using news readers like The Old Reader or Feedbin. They can be an important source of traffic. Because RSS feeds are published in XML markup, a single misplaced comma can ruin a feed, making it unreadable for users. WordPress RSS feeds are also an important source of content for some other applications. For example, if you use IFTTT to promote your posts on social networks, that won’t work either.
