解决方法是添加查询和更新帖子数语句到任务文件中（还有版块fid48）。
$rs28=$db->get_one("SELECT COUNT(*) AS topic FROM pw_threads WHERE fid='28'");
$ts28=$db->get_one("SELECT COUNT(*) AS posts FROM pw_posts WHERE fid='28'");
$article28=$ts28['posts']+$rs28['topic'];
$db -> update("UPDATE pw_forumdata SET benban='$article28' where fid='28'");
