PHP错误，我该如何解决？

Question

我已将网站上传到托管，此网站内有3个子网站，当我浏览它时，会显示上述错误。我应该修改哪个文件？我的配置文件代码如下。

<?php
 date_default_timezone_set('Asia/Calcutta');

// Site Name & Title
 define('SITE_NAME','SREE SHIRIDI SAI HIGH SCHOOL');
 define('SITE_TITLE','SREE SHIRIDI SAI HIGH SCHOOL');

 // Site Path ...
 define('SITE_PATH',$_SERVER['DOCUMENT_ROOT'].'medha/skool');
 define('ADMIN_PATH',SITE_PATH.'/admin');
 define('CSS_PATH',SITE_PATH.'/css');
 define('PHP_PATH',SITE_PATH.'/php');
 define('JS_PATH',SITE_PATH.'/js');
 define('IMAGES_PATH',SITE_PATH.'/imageS');
 define('INC_PATH',SITE_PATH.'/inc');
 define('LIB_PATH',SITE_PATH.'/lib');

 // Site URL's ...
 define('SITE_URL','http://working.fssolutions.in/medha/skool');
 define('ADMIN_URL',SITE_URL.'/admin');
 define('CSS_URL',SITE_URL.'/css');
 define('PHP_URL',SITE_URL.'/php');
 define('JS_URL',SITE_URL.'/js');
 define('IMAGES_URL',SITE_URL.'/images');
 define('INC_URL',SITE_URL.'/inc');
 define('LIB_URL',SITE_URL.'/lib');
 //echo JS_URL;


 // Database Connections Do not Modify Below....
