    I've just upgraded from DNN 7.4.2 to DNN 8.0.4

    I can no longer login to the admin area. I get this error:

               Module Load Warning One or more of the modules on this page did not load. This may be temporary. Please refresh 
                   the page (click F5 in most browsers). If the problem persists, please let the Site Administrator know.

    On the upgrade status report - everything was uploaded successfully. However underneath there was this error:

    ----------------------------------------------------------------------------------------------------------

    This operation requires IIS integrated pipeline mode.

    Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

    Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.8.4210.0

    -----------------------------------------------------------------------------------------------------

     

    I have since changed the IIS setting to 'Integrated' from 'Classic' and recycled the Application Pool and restarted the website. But I still get the same error.

    Do I need to rollback the installation and use 'Integrated' pipeline mode for the upgrade?

    Also, all the Text/HTML modules are blank. Prior to the upgrade I installed CKEditor-Provider_2.1.20.0 - DNN7

      Yes, it probably would make sense to revert, switch IIS to integrated pipeline mode, test, and then try the upgrade again.

      I don't recall any special considerations in going from 7.4.2 to 8.0.4. You may need to tweak skins and containers ...

        just tried another upgrade from DNN 7.4.2 to DNN 8.0.4

        I reverted the IIS application pool to integrated pipeline mode. I was feeling optimistic as there was no reference to the integrated pipeline mode error beneath the installation upgrade report. Eveything appeared to upgrade successfully. However, I still have the same problem and same error (shown below) and cannot login to the admin area. Could this be caused by a dodgy module? I wonder if it's possible to uninstall a few modules as a test - to narrow down the problem?

          Yes, it could be a module.

          It could also be a theme or a container, particularly if your theme/containers use SolPart menus and controls.

          Take a look at /portals/_default/logs for the most recent log file and look there for errors See what they say.

          You may also be able to login if you browse directly to yoursite.com/login.aspx.

            looking in my logs, i did find a reference to solpart...

                   Could not load type 'DotNetNuke.UI.WebControls.SolPartActions

            I removed a few references to solpart...

                 <%@ Register TagPrefix="dnn" TagName="ACTIONS" Src="~/Admin/Containers/SolPartActions.ascx" %>

            from the web.config and a few more files and then i could login as an admin user, but couldn't opne admin page or host area.

             I then removed all above lines from all other files (about 90 locations - find and replaces from the portals folder) and now the admin area crashes.

            maybe it's best to push back the install again and use another skin for the admin? (i'm not entirely sure what solpart is?)

              Bingo!

              I think you can simply removed all such references in the containers.

              The skin itself is a bit more difficult.

              But, that's pretty much your problem.

                sorted now.

                just removed other references to DNNActions etc in the containers.

                as shown here:

                  I would also go back and remove any "Register" statements in the containers that refer to SolPart.

                  It's also a good idea, probably, to check your skin/theme files and verify that you are not using SolPart there either. But, because your theme seems to be working, you probably don't have a SolPart problem there. Still, I'd check.

                    ...just when you thought it was safe to go back into the water!

                    i thought it was sorted, but then next time i logged in, the problem reoccurred and i couldn't get back into the admin area despite deleting all references to the solpart actions.

                    I've rolled back my database again to 7.4.2 and going to try again.

                    i was wondering if there is anything else i can do in version 7 prior to the upgrade? - should i remove the solpart menu first? and install another alternative menu system? (telerik / DDR menu)?
