Usually there's a message in the event viewer regarding to the error. Possibly it's because you have the validation element in there twice. As well as the system.webserver element.

Solution 1

You are getting errors because you have elements defined multiple times in your configuration. You need to remove the top system.webServer section, and you only need <validation validateIntegratedModeConfiguration="false"/> once.

Solution 2

Check all the Web.Config element tags are closed properly. Probably you should remove the multiple entries of elements like

XML

<system.webserver>

and

XML

<validation>

too.
