To disable comments in general, go to your wp-admin panel. Then open Settings > Discussions. There you can disable “allow people to submit comments on new posts”.
If you only want to disable comments for certain FAQs, then open a post and see discussions box. There you can uncheck “Allow Comments”.
You can also disable comments for all frequently asked question post types. Simply put the following code into your functions.php file.
function disable_comments_for_faq_post_types( $open, $post_id ) { $post_type = get_post_type( $post_id ); // disable comments for built-in "faq" post type if ( $post_type == 'faq' ) { return false; } // enable comments for any other post types return true; } add_filter( 'comments_open', 'disable_comments_for_faq_post_types', 10 , 2 );
