Hello,

We using umbraco 4.72. We had hosted the site on a staging servers without any problems. Recently we have migrated the site to our live environment. Post the migration, the website is functional but the umbraco back end editor returns the following error message - "HTTP Error 500.22 - Internal Server Error. An ASP.NET setting has been detected that does not apply in Integrated managed pipeline mode.". Below is the detailed error information

Module ConfigurationValidationModule

Notification BeginRequest

Handler ExtensionlessUrlHandler-Integrated-4.0

Error Code 0x80070032

Logon Method Not yet determined

Logon User Not yet determined

Please note that the version of webserver and IIS on the live environment where the problem occurs - 

Windows Server 2008 R2

V 6.1 (Build 7601: Service Pack 1)

IIS version 7.5.7600.16385

As per the forum posts, we have ensured that the following web.config fragment exists but with no results - 

<System.webServer>

    <validation validateIntegratedModeConfiguration="false" />

</System.webServer>

Please can you shed some light on this and how we can resolve this?

Regards

Shwetha
