This custom function should help removing all links in the header and footer – you may put it inside the functions.php file of your active theme:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 | function remove_json_api () { // Remove the REST API lines from the HTML Header remove_action( 'wp_head', 'rest_output_link_wp_head', 10 ); remove_action( 'wp_head', 'wp_oembed_add_discovery_links', 10 ); // Remove the REST API endpoint. remove_action( 'rest_api_init', 'wp_oembed_register_route' ); // Turn off oEmbed auto discovery. add_filter( 'embed_oembed_discover', '__return_false' ); // Don't filter oEmbed results. remove_filter( 'oembed_dataparse', 'wp_filter_oembed_result', 10 ); // Remove oEmbed discovery links. remove_action( 'wp_head', 'wp_oembed_add_discovery_links' ); // Remove oEmbed-specific JavaScript from the front-end and back-end. remove_action( 'wp_head', 'wp_oembed_add_host_js' ); // Remove all embeds rewrite rules. add_filter( 'rewrite_rules_array', 'disable_embeds_rewrites' ); } add_action( 'after_setup_theme', 'remove_json_api' ); |
