How can I edit the content of the RSS feed?
You shouldn’t ever need to customise your podcast RSS feed template, but, if you must then open up the plugin folder and navigate to the
templatesdirectory. From there copy the
feed-podcast.phpfile and paste it into the root folder of your theme (or child theme).
This file in your theme will now control the data that is displayed in the podcast RSS feed, so any changes you make in there will affect your feed.
