问题描述
I get this error when trying to serve my PHP code from Apache: 
当尝试从Apache服务我的PHP代码时出现此错误：
Notice: Undefined variable: COMMUNITY in /var/www/Account/assets/includes/head/nav.php on line 1
Fatal error: Uncaught Error: Call to a member function getUser() on null in /var/www/Account/assets/includes/head/nav.php:1 Stack trace: #0 /var/www/Account/assets/includes/head.php(60): include_once() #1 /var/www/Account/cpanel/community.php(3): include('/var/www/Accoun...') #2 /var/www/Account/assets/classes/core.php(14): require_once('/var/www/Accoun...') #3 /var/www/Account/assets/includes/head.php(7): require_once('/var/www/Accoun...') #4 /var/www/Account/cpanel/home.php(3): include('/var/www/Accoun...') #5 {main} thrown in /var/www/Account/assets/includes/head/nav.php on line 1
On XAMPP in Windows it's working, I don't get the error; 在Windows的XAMPP上可以正常工作，但我没有收到错误； but on Linux with Apache doesn't. 但在具有Apache的Linux上却没有。 Both use PHP 7.1 两者都使用PHP 7.1

I've finally fixed by setting in core.php 我终于通过设置core.php来解决
<?php
require_once(ROOTPATH.'/../classes/user.php');
$USER = new USER();
require_once(ROOTPATH.'/../classes/community.php');
$COMMUNITY = new COMMUNITY();
It seems like it wasn't getting the proper file 好像没有得到正确的文件
