I keep getting this error:
An exception of type 'System.Web.HttpException' occurred in System.Web.dll but was not handled in user code
Additional information: Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. Please also make sure that System.Web.SessionStateModule or a custom session state module is included in the <configuration>\<system.web>\<httpModules> section in the application configuration.
I've tried following the above suggestions but it seems to make no difference.
