$url = new KBUrl();
$next_page_url = $url->set('uid', $execute_uid)->set('mod', 'document')->toString();
$next_page_url = apply_filters('kboard_after_executing_url', $next_page_url, $execute_uid, $board_id);
wp_redirect($next_page_url);

이러한 코드가 있습니다.

$next_page_url = $url->set('uid', $execute_uid)->set('mod', 'document')->toString();

위 코드를 아래코드로 변경해보세요.

$next_page_url = $url->set('mod', 'list')->toString();

더 좋은 방법은 kboard_after_executing_url 필터를 사용해서 변경해주세요.
