    Hi,

    Object reference not set to an instance of an object.   at Microsoft.SharePoint.Publishing.Navigation.PortalSiteMapNode.GetNavigationChildren(NodeTypes includedTypes, NodeTypes includedHiddenTypes, Boolean securityTrimmingEnabled, OrderingMethod ordering, AutomaticSortingMethod method, Boolean ascending, Int32 lcid)
       at Microsoft.SharePoint.Publishing.Internal.CodeBehind.AreaNavigationSettingsPage.AddChildrenToControl(String parentId, PortalSiteMapNode node, Int32 depth, Int32 maxDepth)
       at Microsoft.SharePoint.Publishing.Internal.CodeBehind.AreaNavigationSettingsPage.AddChildrenToControl(String parentId, PortalSiteMapNode node, Int32 depth, Int32 maxDepth)
       at Microsoft.SharePoint.Publishing.Internal.CodeBehind.AreaNavigationSettingsPage.InitializeNavigationEditSort()
       at Microsoft.SharePoint.Publishing.Internal.CodeBehind.AreaNavigationSettingsPage.OnLoad(EventArgs e)
       at System.Web.UI.Control.LoadRecursive()
       at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

    Error telling me that this is publishing portal and at the time of constructing top or left navigation control, it coudn't get the node. Please check "Modify Navigation" from Site settings also if you have changed anything related to navigatin in master page like navigation provider, control then check it again.

    Thanks for your information. If you dont mind can you please elaborate these two points. I am not able to traverse to Modify Navigation as it fires the null reference exception.Where exactly to check the issue and what to modify.

     

    Thank you.
