Remove: "Server Error in '/' Application" Custom error

[eUK-Martin]

Hello,

There are so many clients who see the ASP .NET custom error below and don't know how to get the exact error:

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>

To remove this custom error and get the exact error just follow the steps below:

1. Open your web.config and find the line "</system.web>".
2. Add the link below just above it:
"<customErrors mode="Off" />"
to make look as:

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

4. Save the config file and refresh the page and you will see the exact error on the screen.

If you already have a line uncommented:

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

then change it to:

<customErrors mode="Off" defaultRedirect="mycustompage.htm"/>
