You will find this code in wp-comments-post.php
I found it out myself.
What to do:
Find
$location = apply_filters(‘comment_post_redirect’, $location, $comment);
Change it to
$location = apply_filters(‘comment_post_redirect’, $redirect_to);
Add above
$redirect_to = ‘index.php’;
So you will get
$redirect_to = ‘index.php’;
$location = empty($_POST[‘redirect_to’]) ? get_comment_link($comment_id) : $_POST[‘redirect_to’] . ‘#comment-‘ . $comment_id;
$location = apply_filters(‘comment_post_redirect’, $redirect_to);
Maybe it helps when I show you my WordPress for some testing.
