做好的网站上传到空间有Server Error in '/' Application 高手帮帮忙啊 　 来源：BBS.TONGJI.NET

自己做好个网站想传到空间上去，自己机子上调试是正常的，传到空间后，数据库的连接也改过
但是出来这个

Server Error in '/' Application. Runtime Error Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.

Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".

<!-- Web.Config Configuration File --><configuration> <system.web> <customErrors mode="Off"/> </system.web></configuration>

Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.

<!-- Web.Config Configuration File --><configuration> <system.web> <customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/> </system.web></configuration>

我按照它说的将customErrors mode设为off了 ，还是这样
真是疯掉了，高手谁能帮帮我
