为什么我的网站在自己电脑上运行是正确的，到服务器上就出错呢？
错误代码是：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>
 
麻烦好心人看看

------解决方案--------------------
检查服务器.net版本和iis中asp.net版本的设置
检查数据库连接

你的这个错误是通用错误页面，任何一个错误都会这样显示
------解决方案--------------------
服务器是否支持.net的版本，数据库是否开通。
