    After upgrading to DNN 9.3 from 9.1.1 I am getting this error:

    DotNetNuke.Services.Exceptions.PageLoadException: Object reference not set to an instance of an object. ---> System.NullReferenceException: Object reference not set to an instance of an object.

--- End of inner exception stack trace ---

    Any ideas/clues?

      Upgrading to DNN 9.2.0 and higher puts you in the realm of several breaking changes that need to be fixed.

      You should check the files in portals/_default/logs to see if there is other information there that will help to identify the module/modules that need upgrading.

      Step #1 would be to look at all of the installed modules and see if your modules are compatible with DNN 9.2.0 and higher. If not, you'll need to get upgraded versions of the modules and install them.

        That was from the Logs folder.  The website does not come up at all, and that's the only information I have.

        I get a "DNN Error" with a "Return to Site" button.

         

        Here are the log entries:

          Figured it out.

          SELECT * FROM dbo.JavaScriptLibraries

          And checked and I had jQuery missing, and in /Resources/Libraries there was a hick-up on the upgrade, version 1.9.1 was still there.
