When I go to the Admin menu and select File Manager, and then click the File Upload button I get the following error:

Error: Upload File is currently unavailable.DotNetNuke.Services.Exceptions.ModuleLoadException: Object reference not set to an instance of an object. ---> System.NullReferenceException: Object reference not set to an instance of an object. at DotNetNuke.Services.FileSystem.FolderManager.GetFolders(Int32 portalID, String permissions, Int32 userID) at DotNetNuke.Modules.Admin.FileManager.WebUpload.LoadFolders() at DotNetNuke.Modules.Admin.FileManager.WebUpload.OnLoad(EventArgs e) --- End of inner exception stack trace ---

When I perform the same steps through the Host menu, everything works fine. It seems to be specific to the Admin level. I've resync'd the folders using the recursive option, cleared the cache still no help.

Any ideas what is going on and how to fix this? Everything was working fine until yesterday and then this just popped up.

We are using DNN Pro 06.01.03 (108).

thanks in advance.

Hi Dan,

What was the resolution to your File Manager upload issue?  We have been chasing the same problem and haven't located the fix yet.

Thank you

We are also running DNN Pro 6  (6.2.6) with a planned upgrade to 8 in the spring. We have worked with support for a while on the issue but the problem still exists.  I was hoping someone in the community might have solved this.

fyi: just under 15,000 user accounts and lots of image and document files exist on the site.
