独立服务器，PHP和mysql运行正常，
ECSHOP运行了很长时间，近日突然出现奇怪的现象：
1、前台一切正常
2、后台登陆页面出错，提示信息如下：

ECSHOP info: Can't Connect MySQL Server()!


初看之下，以为是mysql的账号密码有误，遂将mysql和ecshop的配置文件（data/config.php)中数据库账号密码部分重新设置配置，前台仍然正常显示，后台还是显示上面的错误信息。

我的理解是，前台都能正常连接到mysql，说明mysql的账号密码无误，那是后台有单独的配置文件吗？看到includes/init.php文件中有说到include('../includes/config.php');
可是在根目录includes目录下和admin目录下的includes目录，均未找到有config.php目录，是这个文件被删除了吗？

求教！

真冷场啊……

数据库链接文件没有修改阿

除了config.php还有哪里有配置文件？
