您可以尝试使用此代码。完全删除backed中的注释功能。

将此代码放在当前主题函数中。php文件。

<?php
// Removes from admin menu
add_action( \'admin_menu\', \'my_remove_admin_menus\' );
function my_remove_admin_menus() {
    remove_menu_page( \'edit-comments.php\' );
}
// Removes from post and pages
add_action(\'init\', \'remove_comment_support\', 100);

function remove_comment_support() {
    remove_post_type_support( \'post\', \'comments\' );
    remove_post_type_support( \'page\', \'comments\' );
}
// Removes from admin bar
function mytheme_admin_bar_render() {
    global $wp_admin_bar;
    $wp_admin_bar->remove_menu(\'comments\');
}
add_action( \'wp_before_admin_bar_render\', \'mytheme_admin_bar_render\' );
?>

将此代码添加到函数中。php。它检查用户是否是管理员，或者是否可以调节其他用户的帖子。
