RE:Unable to cast object of type 'System.Web.UI.PartialCachingControl'
What are you trying to set manually, you can use in CMS Desk. Could you please try to set the page level cache in the CMS Desk -> select some document (e.g. root) -> Properties -> General -> Cache at the bottom?
Here you can find more information about the full-page cache - http://www.kentico.com/docs/devguide/caching_options.htm
I hope it will help.
