'/2013' 应用程式中发生伺服器错误。

执行阶段错误

描述: 伺服器上发生应用程式错误。此应用程式的目前自订错误设定因安全性考量，防止他人从远端看见应用程式错误的详细资讯。然而，可以使用本机伺服器电脑上的浏览器检视。

详细资料: 若要在远端电脑检视此特定错误讯息的详细资讯，请于目前 Web 应用程式根目录内的 "web.config" 组态档中建立 <customErrors> 标记。然后将 <customErrors> 标记的 "mode" 属性设为 "Off"。


<!-- Web.Config 组态档 -->

<configuration>
    <system.web>
        <customErrors mode="Off"/>
    </system.web>
</configuration>

注意: 可以藉由修改应用程式 <customErrors> 组态标记的 "defaultRedirect" 属性，使其指向自订错误页面的 URL，以便使用自订错误页面取代您目前看到的错误页面。


<!-- Web.Config 组态档 -->

<configuration>
    <system.web>
        <customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/>
    </system.web>
