我登陆igenus web界面的两个问题

lues

我用http://qmailtest.newsky.cn:83/webmail/src/login.php登陆，则系统出现如下提示

Warning: main(../config/config.php): failed to open stream: 权限不够 in /usr/share/squirrelmail/functions/global.php on line 16

Fatal error: main(): Failed opening required '../config/config.php' (include_path='.:/usr/share/pear') in /usr/share/squirrelmail/functions/global.php on line 16

我用http://qmailtest.newsky.cn:83/igenus/login.php登陆则登陆页面能够正常访问，但是输入用户名密码后登陆后则出现如下提示，请问该怎么解决，谢谢

目录权限不够。根据错误报告里的目录调整一下权限。

重配了一下，用http://qmailtest.newsky.cn:83/igenus/login.php用户能够登陆了，但是一点击收件箱什么的就出现以下提示：

我把display_errors = On
改为display_errors = Off了
再把
session.bug_compat_42 = 1
session.bug_compat_warn = 1
改为了
session.bug_compat_42 = 0
session.bug_compat_warn = 0
