HTTP Error 500.24 - Internal Server Error

An ASP.NET setting has been detected that does not apply in Integrated managed pipeline mode.

Most likely causes:

• system.web/identity@impersonate is set to true.

Things you can try:

• If the application supports it, disable client impersonation.
• If you are certain that it is OK to ignore this error, it can be disabled by setting system.webServer/validation@validateIntegratedModeConfiguration to false.
• Move this application to an application pool using Classic .NET mode - for example, %SystemRoot%\system32\inetsrv\appcmd set app "Default Web Site/" /applicationPool:"Classic .NET AppPool"

(You can set "Classic .NET AppPool" to the name of another application pool running in Classic managed pipeline mode)

It started working once I changed from
