把 /applications/vanilla/views/discussions/helper_functions.php 复制到你主题目录的 /views/discussions/helper_functions.php

找到以下变量，并修改成代码：

$DiscussionUrl = '/discussion/'.$Discussion->DiscussionID.'/'.($Discussion->CountCommentWatch > 0 && C('Vanilla.Comments.AutoOffset') && $Session->UserID > 0 ? '/#Item_'.$Discussion->CountCommentWatch : '');
