I have been going through the upgrade steps from 4.9.5 to 6.1.4 and just about alls seems to work except the update said there was a DDRMenu error (won't let me do a repair install).

Everything pretty much seems to be ok except the Host Settings page won't load and gives the error:

Error: Host Settings is currently unavailable. DotNetNuke.Services.Exceptions.ModuleLoadException: An item with the same key has already been added. ---> System.ArgumentException: An item with the same key has already been added. at System.ThrowHelper.ThrowArgumentException(ExceptionResource resource) at System.Collections.Generic.Dictionary`2.Insert(TKey key, TValue value, Boolean add) at System.Linq.Enumerable.ToDictionary[TSource,TKey,TElement](IEnumerable`1 source, Func`2 keySelector, Func`2 elementSelector, IEqualityComparer`1 comparer) at DotNetNuke.Entities.Modules.ModuleControlController.GetModuleControlsByModuleDefinitionID(Int32 moduleDefID) at DotNetNuke.Modules.Admin.Host.HostSettings.BindData() at DotNetNuke.Modules.Admin.Host.HostSettings.OnLoad(EventArgs e) --- End of inner exception stack trace ---

Does anyone know what might be wrong here and how it could be fixed?

Thanks

Hi Tom

Thanks for the reply.

I've switched to the DarkKnight skin but unfortunately the error with the Host settings still appears as before.

Dave,

I took a look at the code where the first exception is occurring. Examine the database (after the upgrade to 6.1.3 or 6.1.4) table ModuleControls looking in particular for rows that have a null ModuleDefID and the same ControlKey and let me know what you find. I suspect that the ControlKey that is duplicated might be CONTROLPANEL:RibbonBar.

As for the second exception I don't think that is related to the first and since the ActiveTabID is -1 may be occurring when processing a scheduled job rather than when a user hits a particular page.
