Understanding Submission Errors
A runtime error indicates an issue with an application on the server. Due too security configurations, specific error details might not be visible remotely. These details are typically accessible when the application is run on the local server.
Accessing Error Details
To view detailed error information on a local machine, modify the <customErrors> tag within the web.config file, located in the application’s directory. Set the mode attribute of the <customErrors> tag to “Off.”
Custom Error Pages
The default error page can be replaced with a custom one. This is achieved by using the defaultRedirect attribute within the <customErrors> configuration. This attribute should point to the URL of the custom error page.

Understanding Runtime Errors
A runtime error indicates a problem occurring while an application is running on the server.These errors prevent the application from functioning correctly and frequently enough result in either a partial or complete failure of the intended process. Runtime errors can manifest in various forms, frequently prompting developers to troubleshoot for the root cause.
Why Can’t I See the Specific Details of a Runtime Error?
Due to security configurations, specific error details might not be visible remotely. This is a common practice to protect sensitive information and prevent potential vulnerabilities. While this enhances security, it can make troubleshooting complex as the exact nature of the runtime error is frequently enough obscured.
How Do I Access Detailed Error Information?
Detailed error information is typically accessible when the application is run on the local server. This allows developers to directly interact with the error and pinpoint the source of the problem.
To view detailed error information on a local machine, modify the <customErrors> tag within the web.config file, located in the application’s root directory.
How to Modify web.config for Error Details
Here’s how to modify your web.config file:
- Locate the
web.configfile: Find the file in your application’s directory on your local server. - Open the
web.configfile: Use a text editor or code editor to open the file. - Find the
<customErrors>tag: Search for this tag within the file. If it doesn’t exist, you may need to add it. - Set the
modeattribute to “Off”: Inside the<customErrors>tag, ensure themodeattribute is set to “Off.” This will disable custom error handling and display detailed error messages.

How to Implement Custom Error pages

Here’s how to set a custom error page in the web.config file:
- Find the section in your
web.configfile: Locate the section in theweb.configfile or add the tag. - Add the
defaultRedirectattribute: Use thedefaultRedirectto point to the URL of your custom error page.
An Example showing `<customErrors defaultRedirect =”/error.htm” mode=”RemoteOnly” />`
A comprehensive guide on custom error pages can be found in online documentation.
