I upgraded a site from 4.0.3 to 4.3.6. I access the filemanager from either the admin or host.

Below are the exceptions I get.

An error has occurred.
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. at DotNetNuke.Security.Permissions.Controls.FolderPermissionsGrid.SaveViewState() at System.Web.UI.Control.SaveViewStateRecursive() at System.Web.UI.Control.SaveViewStateRecursive() at System.Web.UI.Control.SaveViewStateRecursive() at System.Web.UI.Control.SaveViewStateRecursive() at System.Web.UI.Control.SaveViewStateRecursive() at System.Web.UI.Control.SaveViewStateRecursive() at System.Web.UI.Control.SaveViewStateRecursive() at System.Web.UI.Control.SaveViewStateRecursive() at System.Web.UI.Control.SaveViewStateRecursive() at System.Web.UI.Control.SaveViewStateRecursive() at System.Web.UI.Control.SaveViewStateRecursive() at System.Web.UI.Control.SaveViewStateRecursive() at System.Web.UI.Control.SaveViewStateRecursive() at System.Web.UI.Control.SaveViewStateRecursive() at System.Web.UI.Control.SaveViewStateRecursive() at System.Web.UI.Page.SaveAllState() at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) --- End of inner exception stack trace ---

Access the log viewer I see the following exceptions being logged.

Any thoughts would be of great help. The exceptions don't seem to have provide any useful information.

Hmm, I've seen some issues with the upgrade in the file manager, mainly due to the information stored about files in DNN.

I think most people that had this problem had to clear out the files table in DNN.

Here is another thread with someone else having issues in the file manager.

Not much luck in truncating the Files and Folders tables. Now since I can no longer access the File Manager to syncrhonise the file system, what other way can I do it? I see something in the Host settings with auto synchonising. Is this how you should do it?

Cheers
Paul.
