After installing Dnn without any major issues. When I try to access the site for the first time I get the Dnn Error page.
When I checked on the EventLog table I saw that the exception was :

"DotNetNuke.Services.Exceptions.PageLoadException: Object reference not set to an instance of an object. ---> System.NullReferenceException: Object reference not set to an instance of an object.
at DotNetNuke.Framework.DefaultPage.OnInit(EventArgs e)
at System.Web.UI.Control.InitRecursive(Control namingContainer)
at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)
--- End of inner exception stack trace "

I tried google but it didn't help much.

I'm running iis 8 on windows 8 and trying to install dnn 7.1.1

Any help will be enormously apretiated
