In versions of Genesis prior to 2.6, Custom RSS Feed settings could be found on the Genesis > Theme Settings screen. However, these settings were removed in Genesis 2.6, making them inaccessible through the WordPress dashboard.
Here’s the code to eliminate a feed redirect that was set up before Genesis 2.6, as well as the link to that feed in the source code:
remove_action( 'template_redirect', 'genesis_feed_redirect' ); remove_filter( 'feed_link', 'genesis_feed_links_filter', 10, 2 );
