Common Runtime Error: Troubleshooting and Solutions
What is a Runtime Error?
A runtime error is a problem that occurs while a program is running. it signals that the program is unable to proceed due to an issue it encountered during its execution. The specific error’s root cause can vary widely, but the symptom is a disruption in the application’s normal operation.
What Does “Submission Error Has Occured on the Server” Meen?
This message indicates that something went wrong when data was being submitted to the server. The error prevents the application from working correctly. The details about the error are deliberately hidden for security reasons.
Why Can’t I See the Error Details?
For security purposes,the server’s current settings are configured to prevent detailed error messages from being displayed remotely. Displaying these details could expose sensitive data and make the application vulnerable to attack.
How Can I View the Error Details?
To view the full details of the runtime error, you need to adjust the server configuration. You can do this by making changes to the web.config file:
Editing the web.config File
- Locate the
web.configfile: This file is situated in the root directory of your web application. - Add or Modify the
- Set
mode="Off": Within themodeattribute to"Off". This enables the display of detailed error messages.
xml
<customErrors mode="Off" />

- Modify the
defaultRedirectattribute: Within thedefaultRedirectattribute to the URL of your custom error page,such as yourcustomerrorpage.htm. - Set
mode="RemoteOnly": To manage when the custom error page is presented, usemode="RemoteOnly". This shows your custom error page to remote users while allowing local users (those on the server machine) to see the detailed error information.
xml
<customErrors defaultRedirect="yourcustomerrorpage.htm" mode="RemoteOnly" />
Note: Ensure that the URL for your custom error page is correct.
