I had tried the script that can fix this issue in the old version. But it's doesn't work this time. The up & down arrow disappear so I can change the category order.

Is there any new script I can use to fix this issue?

It doesn't work on my website. Did I miss something?

I copy

if exists (select * from dbo.sysobjects where id = object_id(N'{databaseOwner}[{objectQualifier}Help_ListCategoryByParent]') and OBJECTPROPERTY(id, N'IsProcedure') = 1)
 drop procedure {databaseOwner}[{objectQualifier}Help_ListCategoryByParent]
GO

CREATE PROCEDURE {databaseOwner}[{objectQualifier}Help_ListCategoryByParent]

@ModuleID int,
@ParentID int
 
AS
SELECT   [CategoryID],
   [CategoryGUID],
   [Name],
   [Description],
   [Image],
   [KeyWords],
   [ModuleID],
   [Order],
   [Level],
   [Parent],
   [Visible],
   [Deleted]

FROM   {databaseOwner}{objectQualifier}Help_Category

WHERE  [Parent] = @ParentID AND [ModuleID] = @ModuleID
AND   [Deleted] <> 1

ORDER BY [Level] ASC,
   [Parent] ASC,
   [Order] ASC
   
GO

to the SQL and choose "run as script" then click "Exeute". The answer is "The Query completed successfully! " But it doesn't work.

This issue only happened on upgrade process, I don't have this problem if I install a new DNN installation. But I have wrote a lot of content in old help module. I try to export the content but fail. I trace the source code. I think there some problem let this module "hide" this two icon. (Can't find previous category & can't find next category.)

Is there any solution can fix this issue? I wish to un-install, intall help module can fix this issue. But I need to backup the help content first(But I can't now.).
