Hi guys
We run a community over DNN and we are facing strange problems. Sometimes we get following error messages while browsing through the site:
1. A critical error has occurred.
Object reference not set to an instance of an object.
2. A critical error has occurred.
Unable to cast object of type 'ASP.admin_skins_modulemessage_ascx' to type 'System.Web.UI.HtmlControls.HtmlGenericControl'.
3. A critical error has occurred.

These are those frequent errors which occurred at random while browsing through site. We can't rectify why these errors occur?
Please help us in solving this problem.
