    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.

    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 ...
