Answer 1

require substr(MOD_ROOT, 0, -1-strlen($mod)).'include/common.inc.php'; 
D:\PHPnow\htdocs\include/common.inc.php
一個左\一個右/
估計無法識別
還得得確認你是否有這個文件D:\PHPnow\htdocs\include\common.inc.php你是common.inc.php rquire common.inc.php 不知道有沒有死機現象

Answer 2

把/都改成DIRECTORY_SEPARATOR定量就可以了。如下：
require substr(MOD_ROOT, 0, -1-strlen($mod)).'include'.DIRECTORY_SEPARATOR.'common.inc.php';
