求救啊~~ “/”应用程序中的服务器错误。

部署在服务器上的项目...  以前还能访问..最近突然就出现这个问题运行时错误 
说明: 服务器上出现应用程序错误。此应用程序的当前自定义错误设置禁止远程查看应用程序错误的详细信息(出于安全原因)。但可以通过在本地服务器计算机上运行的浏览器查看。 详细信息: 若要使他人能够在远程计算机上查看此特定错误消息的详细信息，请在位于当前 Web 应用程序根目录下的“web.config”配置文件中创建一个 <customErrors> 标记。然后应将此 <customErrors> 标记的“mode”属性设置为“Off”。
<!-- Web.Config 配置文件 --><configuration>
    <system.web>
        <customErrors mode="Off"/>
    </system.web>
</configuration>
 注释: 通过修改应用程序的 <customErrors> 配置标记的“defaultRedirect”属性，使之指向自定义错误页的 URL，可以用自定义错误页替换所看到的当前错误页。
<!-- Web.Config 配置文件 --><configuration>
    <system.web>
        <customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/>
    </system.web>
</configuration>

    这个错误。。只要LZ用发帖的关键字去搜索一下我想答案立马就出来了CSDN一天总有几帖是问这个的
      

  3.   


    先把customErrors设为<customErrors mode="Off"/>看看报错的详细信息。。一般无非是权限问题和Asp.net的版本
      

  4.   

    权限问题或asp.net版本问题，一般就是这两个。
      

  5.   

    <configuration>
      <system.web>
      <customErrors mode="Off"/>
      </system.web>
    </configuration>
     你在web.config中加入这段，看看具体错误，
      

  6.   


    你把这句话加入到服务器上吗的web.config里面，在查看错误我想这个应该是连接字符串的错误了，你把data source= ./ 换成远程数据库的IP试试吧
