執行階段錯誤

'/2013' 應用程式中發生伺服器錯誤。

執行階段錯誤

描述: 伺服器上發生應用程式錯誤。此應用程式的目前自訂錯誤設定因安全性考量，防止他人從遠端看見應用程式錯誤的詳細資訊。然而，可以使用本機伺服器電腦上的瀏覽器檢視。

詳細資料: 若要在遠端電腦檢視此特定錯誤訊息的詳細資訊，請於目前 Web 應用程式根目錄內的 "web.config" 組態檔中建立 <customErrors> 標記。然後將 <customErrors> 標記的 "mode" 屬性設為 "Off"。


<!-- Web.Config 組態檔 -->

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

注意: 可以藉由修改應用程式 <customErrors> 組態標記的 "defaultRedirect" 屬性，使其指向自訂錯誤頁面的 URL，以便使用自訂錯誤頁面取代您目前看到的錯誤頁面。


<!-- Web.Config 組態檔 -->

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