1、我在安装plone的ubuntu主机上用firefox访问plone站点，用http://127.0.0.1:8081/sy85ms访问正常，如果用http://10.2.2.251:8081/sy85ms则出现下列错误：

Troubleshooting Suggestions
* The URL may be incorrect.
* The parameters passed to this resource may be incorrect.
* A resource that this resource relies on may be encountering an error.
For more detailed information about the error, please refer to error log.
If the error persists please contact the site maintainer. Thank you for your patience. 2、plone站点首页左上角的plone图片怎么修改成自己的图片，如果要对界面进行大幅度修改，需要编辑哪个文件？
3、如果将http://10.2.2.251:8081/sy85ms按照精华帖子的方法映射成http://10.2.2.251，那么我的其它服务的URL地址应该如何修改呢？例如原先的图片资料数据库http://10.2.2.251/gallery，流媒体服务器http://10.2.2.251:8888，应该如何修改呢？
你先摸索，等年后，我会写一些详细的指南来说明plone的配置。
