I'd like to completely disable RSS feeds on my WP website. Can someone please guide me on how to throw a 404.php page and set the headers to 404, when someone types in https://example.com/feed/

here is the code in functions.php:

function disable_feeds() {    
    global $wp_query;
    $wp_query->is_feed = false;
    $wp_query->set_404();
    status_header( 404 );
    nocache_headers();
    wp_die( __('No feed available,please visit our <a href="'. get_bloginfo('url') .'">homepage</a>!') );
}
 
add_action( 'do_feed',      'disable_feeds', 1 );
add_action( 'do_feed_rdf',  'disable_feeds', 1 );
add_action( 'do_feed_rss',  'disable_feeds', 1 );
add_action( 'do_feed_rss2', 'disable_feeds', 1 );
add_action( 'do_feed_atom', 'disable_feeds', 1 );

add_action( 'do_feed_rss2_comments', 'disable_feeds', 1 );
add_action( 'do_feed_atom_comments', 'disable_feeds', 1 );

add_action( 'feed_links_show_posts_feed',    '__return_false', 1 );
add_action( 'feed_links_show_comments_feed', '__return_false', 1 );

Strangely, I get a 500 Internal Server Error when typing https://example.com/feed/

no corresponding rules are set in .htaccess file Thanks in advance.

You need to define the HTTP Response code in wp_die function.

wp_die( __('No feed available,please visit our <a href="'. get_bloginfo('url') .'">homepage</a>!'), '', 404 );

If I want to bail out of my WP, I do it like this:

    $wp_query->set_404();
    status_header( 404 );
    get_template_part( 404 );
    exit();

I'm actually not sure, why you get a 500 error. I'd try to comment out the lines of your function one-by-one and see, where the error occurs.

  • Thanks Chris, I followed your instructions. This has resolved the Error 500. However, the browser keeps thinking it is still an RSS feed by not displaying the HTML page and prompting to open a RSS reader app.. Any ideas how fix that? – api2_go Nov 2 '20 at 5:27
  • Hm, I found this on the web, but looks pretty much the same, as you already have. function wpb_disable_feed() { wp_die( __('No feed available,please visit our <a href="'. get_bloginfo('url') .'">homepage</a>!') ); } add_action('do_feed', 'wpb_disable_feed', 1); add_action('do_feed_rdf', 'wpb_disable_feed', 1); add_action('do_feed_rss', 'wpb_disable_feed', 1); add_action('do_feed_rss2', 'wpb_disable_feed', 1); add_action('do_feed_atom', 'wpb_disable_feed', 1); add_action('do_feed_rss2_comments', 'wpb_disable_feed', 1); add_action('do_feed_atom_comments', 'wpb_disable_feed', 1); – chris_blues Nov 2 '20 at 10:46
  • Additionally, you can remove the header lines remove_action( 'wp_head', 'feed_links_extra', 3 ); remove_action( 'wp_head', 'feed_links', 2 ); – chris_blues Nov 2 '20 at 10:48
  • wpcaptain.com/blog/… This seems to be the most complete one... It even shows, how to block them via .htaccess . – chris_blues Nov 2 '20 at 10:50
  • thanks very much for the link. I saw it before. However, that solution uses a redirect to home url, and it will generate a 301 header, not 404. Do you know if it will have any impact on SEO and search engine crawlers? I've read somewhere it is better not to use a redirect... I guess, I will have to restrict the access via .htaccess as per the solution above – api2_go Nov 3 '20 at 5:22
