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.

I'm getting this error as well, it seems to be related to something in the filesystem that is out of sync with DNN.  I can clear the error by un-checking the "Auto Sync file system" option under Host Settings, ie:

1) Log in as Host

2) go to Host setting \ Advanced Settings \  Other Settings

3) Un-check "Enable File System Auto-Sync"

Hope this helps.

Thanks..

That got it for me... both in the portal w/ the issue and the host.

Been trying to fix that for a while!

I posted a similar error a few days earlier concerning the same problem on version 4.4.0. There doesn't seem to be an exact counterpart. auto-sync is unchecked, but no help. Anyone have any further thoughts.
