Hi, all!
I've just upgraded DNN to 6.0 and no errors occurred during upgrade.
Everything works fine except for pages with Html-modules.
The stack trace is following:


Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.

Hi, all!
I've just upgraded DNN to 6.0 and no errors occurred during upgrade, but after the update occurred the following errors when editing HTML modules:
---------------------------------------------------------------
Error: is currently unavailable.DotNetNuke.Services.Exceptions.ModuleLoadException: Value of '12/31/9999 12:00:00 AM' is not valid for 'SelectedDate'. 'SelectedDate' should be between 'MinDate' and 'MaxDate'. Parameter name: SelectedDate ---> System.ArgumentOutOfRangeException: Value of '12/31/9999 12:00:00 AM' is not valid for 'SelectedDate'. 'SelectedDate' should be between 'MinDate' and 'MaxDate'. Parameter name: SelectedDate at Telerik.Web.UI.RadDatePicker.set_SelectedDate(Nullable`1 value) at DotNetNuke.Modules.Admin.Modules.ModuleSettingsPage.BindData() at DotNetNuke.Modules.Admin.Modules.ModuleSettingsPage.OnLoad(EventArgs e) --- End of inner exception stack trace ---

I am grateful for all the help I can get.

Hey Dan_Ko,

I am having the same problem. Did you find the solution? I upgraded to DNN 6 and get the same error when using the HTML module.

Thanks!
