RSS Base


RSS Base will rewrite all relative link and image tags (<a> and <img>) to include a base URL.

RSS feeds require absolute URLs to both validate and function properly.

Feed readers can become confused when seeing relative paths, because they won’t necessarily know what base URL to use. A suggested update to the RSS standard has not been widely adopted.

This plugin uses code from Gerd Riesselmann


  1. Upload rss-base.php to your /wp-content/plugins/ directory.
  2. Activate RSS Base through the ‘Plugins’ menu in WordPress.
  3. Go to the “RSS Base” options page and set your base URL.


Is a post’s permalink used when determining the absolute URL?

No, currently this plugin only finds every relative link in posts and comments, and prefixes those links with the base URL you choose in your options.
