RSS feed is one of the best feature of WordPress for sharing post. But there are cases where feeds either have little importantce or does not have any roles to play as in static websites, CMS. For all who do not need RSS feature in WordPress it can be disabled with a little effort.
Step 1:
Create a new function in function.php located in your active theme folder like below:
/** * disable RSS feed */ function wp_disable_feed() { wp_die( __('Sorry, no feeds available, return to <a href="'. get_bloginfo('url') .'">homepage</a>') ); } add_action('do_feed', 'wp_disable_feed', 1); add_action('do_feed_rdf', 'wp_disable_feed', 1); add_action('do_feed_rss', 'wp_disable_feed', 1); add_action('do_feed_rss2', 'wp_disable_feed', 1); add_action('do_feed_atom', 'wp_disable_feed', 1);
I told you. Its very easy to disable feeds.
