you have to edit wp-comments-post located at wp root directory.
at the end of the file chage this part:
$location = get_permalink($comment_post_ID);
header(“Location: $location”);
to this:
$location = (empty($_POST[‘redirect_to’])) ? $_SERVER[“HTTP_REFERER”] : $_POST[‘redirect_to’];
if ($is_IIS) {
header(“Refresh: 0;url=$location”);
} else {
header(“Location: $location”);
}
this has been a problem since 1.2. i wonder why it wasnt corrected in strayhorn. anyways… hope it works ??
