Disabling Windows Custom Error Messaging
By default, our Windows hosting accounts display a custom error when applications generate an exception. We display a generic error because the detailed error messages allow a malicious user to obtain sensitive information.
To troubleshoot the error, you can modify your web.config file and specify that a detailed error message displays. A detailed error message helps you to locate the specific code that is causing the issue.
CAUTION: The code samples we provide below do not constitute a complete web.config file. Do not replace your existing web.config file with the code we provide. Before changing your web.config file, we recommend creating a backup.
