Hi

I like the standard website as a starting point. But when I try changing the home node I get:

Stacktrace:

[NullReferenceException: Object reference not set to an instance of an object.]
   umbraco.editorControls.ultimatepicker.ultimatePickerDataEditor.Save() +508
   umbraco.controls.ContentControl.saveClick(Object Sender, ImageClickEventArgs e) +158
   System.Web.UI.WebControls.ImageButton.OnClick(ImageClickEventArgs e) +115
   System.Web.UI.WebControls.ImageButton.RaisePostBackEvent(String eventArgument) +120
   System.Web.UI.WebControls.ImageButton.System.Web.UI.IPostBackEventHandler.RaisePostBackEvent(String eventArgument) +10
   System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument) +13
   System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) +36
   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +5563

When I edit/change the nodes beneath I don't have this problem.

Umbraco version: umbraco v 4.7.0 on a MySQL db, IIS 7, ASP.NET Framework v4.0.

Thanks
