What does this error mean:

 

2016-12-21 16:27:30,716 [www4][Thread:11][INFO] DotNetNuke.Services.Installer.Log.Logger - Manifest file finished successfully.

2016-12-21 16:27:30,872 [www4][Thread:11][FATAL] DotNetNuke.Web.Common.Internal.DotNetNukeHttpApplication - System.InvalidOperationException: Sequence contains no elements

   at System.Linq.Enumerable.First[TSource](IEnumerable`1 source)

   at Dnn.PersonaBar.Extensions.Components.Dto.PackageInfoDto..ctor(Int32 portalId, PackageInfo package)

   at Dnn.PersonaBar.Extensions.Components.InstallController.ParsePackage(PortalSettings portalSettings, UserInfo user, String filePath, Stream stream)

   at Dnn.PersonaBar.Extensions.Services.ExtensionsController.<>c.<ParsePackage>b__18_0(PortalSettings portalSettings, UserInfo userInfo, String filePath, Stream stream)

   at System.Web.LegacyAspNetSynchronizationContext.CallCallbackPossiblyUnderLock(SendOrPostCallback callback, Object state)

 

Comes from this https://github.com/juvander/DotNetNuke-Forum/blob/05.00.07_DNN8/branches/DNN_5/DNN_Forum.dnn

Works just fine in DNN8, but fails with DNN9, any hint what is wrong with the manifest?

Ok, today continuing debugging this and looks like I cannot install any modules anymore, including for example authentication providers coming with DNN. It also fails with this same error... So something went wrong during the upgrade of this site.

Debugging continues...

Still no luck.

When viewing sites there is also this error in the log:

2016-12-23 07:27:14,251 [RD00155D573915][Thread:7][ERROR] Dnn.PersonaBar.Sites.Services.SitesController - System.NullReferenceException: Object reference not set to an instance of an object.

I'm giving up on this and reverting back to DNN8... Have to wait for couple more releases where this hopefully gets fixed!

This personabar stuff is really poor design as it is basically impossible to debug what is happening inside it...
