remove enclosure url from feed

Question

I searched the whole internet, including this website, but there is no written way on how to remove the enclosure url from the WordPress feed. I want to remove it because FeedBurner is adding the image url directly in the email that it is sending to subscribers. The reason doesn't really matter I guess, so simply how to remove enclosure url from the feed?

<enclosure url="https://example.com/wp-content/uploads/2017/04/whatever-image.jpg" length="5873907" type="image/jpeg"/>

the feed also has this line, which I also want to remove:

<media:content url="https://example.com/wp-content/uploads/2017/04/whatever-image.jpg" width="7360" height="4912" medium="image" type="image/jpeg"/>    

any idea on how to do this? everything I tried until now failed, including some answers on this website

You can look if your posts have any assigned enclosure meta keys, that could trigger the rss_enclosure() core function to print the <enclosure> tag. Otherwise you can try this demo plugin:

<?php
/** Plugin Name: Remove RSS Enclosure **/

add_filter( 'rss_enclosure', '__return_empty_string' );

It looks like you've a plugin that's adding the <media:content> tag, e.g. via the rss2_item hook. So check your plugins. Otherwise you can try this demo plugin to remove all extra rss2 items:

<?php
/** Plugin Name: Remove All Extra rss2 Items **/

add_action( 'rss2_head', function()
{
    remove_all_actions( 'rss2_item' );
} );

We can do similar for atom- and rss feeds.

Remember to request the feed with an url cache buster when debugging.
