Hi to all.

I'm trying to upgrade from 7.00.02 to 07.04.00, upgrade process goes perfect, but after it finishes,  and try to view the site I get DNN Error page.

On the event log is a PAGE_LOAD_EXCEPTION on portal base 

<LogProperties>

<LogProperty><PropertyName>AbsoluteURL</PropertyName><PropertyValue>/ALMQAL/Default.aspx</PropertyValue></LogProperty>

<LogProperty><PropertyName>DefaultDataProvider</PropertyName><PropertyValue>DotNetNuke.Data.SqlDataProvider, DotNetNuke</PropertyValue></LogProperty>

<LogProperty><PropertyName>ExceptionGUID</PropertyName><PropertyValue>69b07ed5-9053-4581-9009-d386aa12e9ab</PropertyValue></LogProperty>

</LogProperties>

Any Ideas?

This is the rrror on the view 

c:\inetpub\wwwroot\DNN602QAL\admin\ControlPanel\ControlBar.ascx(21): error CS1061: 'System.Collections.Generic.List<string>' does not contain a definition for 'Any' and no extension method 'Any' accepting a first argument of type 'System.Collections.Generic.List<string>' could be found (are you missing a using directive or an assembly reference?)

I also make a clean installation as a test, and the same error is shown on the logs.

Thanks for your help.
