Thanks @suascat_wp for your reply.
I’m using the Free version of Yoast plugin, and this issue is still there.
I have disabled this setting, and manually injected the following code (in themes’ functions file) in order to remove RSS links from the head
:
remove_action( 'wp_head', 'feed_links_extra', 3 );
remove_action( 'wp_head', 'feed_links', 2 );
remove_action( 'wp_head', 'rsd_link' );
This way my RSS feeds are still working. Thanks anyway.
