All of a sudden, i get an error in my filemanager
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.SavePageViewState() at System.Web.UI.Page.ProcessRequestMain() --- End of inner exception stack trace ---

try to recycle your application by modifying web.config (just edit any comment and save this file).

I had the same problem recently.  Is this version 4.3.5 and did you make any recent upgrades like new modules etc?  I had to uninstall some dlls to fix my problem but let me know the above question first.

I'm afraid recycling by putting some comments in the web.cong did not work out
Is there another way to reset the filemanager, e.g. by reïnstalling the current version of dnn? or re-installing a dll or something?
