    I just previously upgraded my DNN site from 7.3.3 up to 9.4.4 following the suggested upgrade path. I had originall tried to upgrade to version 9.7.2, but I am running a site that is utilizing VB.net and 9.7.2 had a known breaking change addressed in issue https://github.com/dnnsoftware/Dnn.Platform/issues/4138. So I had tried to upgrade to the latest full release of 9.7.0 that did not include that breaking change. The site upgraded and I was able to browse the site normally, but the errors came once I logged in. As soon as I navigated to the /secure-login page, there was already a red box stating that "An error has occurred. An error has occurred", it shows it two times. Nothing is show in the browser devtools as far as console errors or missing files on the network tab. The log shows these two entries:

    2020-11-27 06:42:22,043 [CLSRSDEV01][Thread:61][ERROR] DotNetNuke.Services.FileSystem.FileManager - System.NullReferenceException: Object reference not set to an instance of an object.

       at DotNetNuke.UI.Skins.Controls.Logo.OnLoad(EventArgs e)"

     I was able to login to the Admin section. I started navigating and once I got to the Site Info page, it was all blank. It did not show any options and there was a red box with the stack trace talking about File manage and the logo missing. I tried to troubleshoot it for a while but then rolled the site back to 9.3.2 and tried to upgrade to 9.4.4. This upgrade worked without any issue. I then tried to upgrade to 9.5.0, but this upgrade gave me errors very similar to 9.7.0 errors mentioned above, but at least this time I could see all the settings on the Site Info page.

    Onto the issue at hand, I cannot upgrade past 9.4.4 without receiving this error:

     Failed to load resource: the server responded with a status of 500 ()        /API/InternalServices/FileUpload/loadimage?file=179

    This occurs when I log into the admin section and go to Site Info. 

    In 9.5.0 I can still see the Site Info, only the logo is missing. If I go to later versions the Site Info page is blank and I do not see anything. Upon checking the logs I find these errors:

    The logo file exists and works just fine in 9.4.4.  I have compared all dlls in the bin folder after the upgrade to what comes in the 9.5.0 install package to see if something is out of date. I really do not have a clue how to fix this error and any help would be much appreciated.

      Have you tried upgrading to v9.8 already? The breaking change has been fixed in this release, which should make it possible for you to continue using the VB.NET code as usual. What's more, is that you can uninstall the old file manager and install the new one which does not use Telerik. Hope this helps.

        Thank you so much for your reply Paras, but unfortunately I am unable to upgrade to 9.8.0 and perform the Telerik removal because I am unable to navigate to the Site Assets or Global Assets. If I attempt to navigate to them as instructed in the removal process of step 3: Navigate to Manage > Site Assets via the Persona Bar and remove the Digital Assets Management module from the page, I get sent to 404 page. I am trying to figure out what happened with the File Manager between version 9.4.4 and 9.5.0.

          UPDATE: So I reverted my site back to 9.4.4 and started looking through it for any errors that could have been missed in previous testing and found that when I navigate to the Site Assets and Global Assets pages there is an error in the DevTools console as follow:

          Uncaught Sys.InvalidOperationException: Sys.InvalidOperationException: Type Telerik.Web.UI.Orientation has already been registered. The type may be defined multiple times or the script file that defines it may have already been loaded. A possible cause is a change of settings during a partial update.

          Despite this error, the Site & Global Asset work as intended. I tested all functionality, creation of folders, deletion of folders, upload files, delete files, move files, etc. 

          I do not know if this is causing me the issues I experience in later versions because it was left unfixed prior to upgrading. Once I upgrade to any version after 9.4.4 I can no longer open the Site Assets or Global Assets. I am stumped and really could use some assistance in getting this resolved.

            For that last error, I would check if you have two versions of one of the Telerik dlls.

              Mr. Breumelhof,

              Thank you for your suggestion.  I did find that site and I checked the bin folder and there are only two Telerik dlls there, Telerik.Web.UI.dll and Telerik.Web.UI.Skins.dll. They are the version that was installed during the upgrade from DNN version 9.5.0.

                Fixed similar upgrade issue by adding cryptography to the web.config.

                I can't paste xml content in this message, but you can download the full dnn installation package for the version you are trying to upgrade to, then search inside its web.config for "cryptography" and copy the lines into your web.config after you've performed the upgrade. 

                I assume this was an upgrade bug introduced in 9.5.0.
