在线等，apache+cacti 无法显示，nagios都可以正常

在apache下配置cacti，mysql，snmp，rrdtools，php都已经装了，nagios我都正常使用。但输入http://192.168.15.65/install/index.php 时显示，不知道问题出在那里。cacti的文件，我是直接拷贝到/usr/local/apache/htdocs/ 下的。

HELP ME，自己顶一下。

在php.ini里设置date.timezone=PRC 重启apache 然后再试试

我试过了，还是不行阿。用的是php5.3.6 我把php.ini-production copy到/usr/local/php5/lib/php.ini 不知道路径对不对？

我在 页投加入 ini_set('date.timezone','Asia/Shanghai'); 后错误没有了，页面就显示白纸一张，这是为什么？
