[sociallocker id=”1131″]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>
Có nhiều lỗi đều dẫn đến thông báo lỗi như bên trên,vì vậy để thấy được sự mô tả đầy đủ,chính xác nguồn gốc của những lỗi ấy,hãy thử làm theo sau đây:
Mặc định, những ứng dụng ASP.NET được thiết lập với custom error messages ở chế độ Off.Tuy nhiên một vài công cụ phát triển web,như Visual Studio.NET tạo web.config file với customErrors mode ở chế độ RemoteOnly.Vì vậy để xem chi tiết thông báo lỗi,bạn cần đặt thuộc tính trong customErrors ở chế độ Off trong tập tin cấu hình web.config nằm trong thư mục gốc của ứng dụng web của bạn.
Đổi <customErrors mode=”RemoteOnly”/> thành <customErrors mode=”Off”/>.
Sau đó ,có thể bạn sẽ thấy nguồn gốc gây ra thông báo lỗi như trên,nếu những ứng dụng mà bạn đã cài đặt không cùng làm việc với nhau.
Lối này do Visual Studio .NET không phiên dịch đúng Double Byte Character Set (DBCS) characters
