I've got a site that's been running for a few years. It has been upgraded over time and is currently running version 06.00.00 (2982).

The public pages are working as expected, however I am getting a number of errors in the admin.

1) When I try to copy a page I get the following error: 

Error: is currently unavailable.DotNetNuke.Services.Exceptions.ModuleLoadException: The underlying system threw an exception. The folder has not been added. ---> DotNetNuke.Services.FileSystem.FolderProviderException: The underlying system threw an exception. The folder has not been added. ---> System.NullReferenceException: Object reference not set to an instance of an object. at DotNetNuke.Services.FileSystem.FolderProvider.Instance(String friendlyName) at DotNetNuke.Services.FileSystem.FolderManager.AddFolder(FolderMappingInfo folderMapping, String folderPath) --- End of inner exception stack trace --- at DotNetNuke.Services.FileSystem.FolderManager.AddFolder(FolderMappingInfo folderMapping, String folderPath) at DotNetNuke.Services.FileSystem.FolderManager.AddUserFolder(UserInfo user) at DotNetNuke.Services.FileSystem.FolderManager.GetFileSystemFolders(UserInfo user, String permissions) at DotNetNuke.Modules.Admin.Tabs.ManageTabs.InitializeTab() at DotNetNuke.Modules.Admin.Tabs.ManageTabs.BindTab() at DotNetNuke.Modules.Admin.Tabs.ManageTabs.OnLoad(EventArgs e) --- End of inner exception stack trace ---

2)  When I access the File Manager, I get the following error:

Error: File Manager 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.FolderProvider.Instance(String friendlyName) at DotNetNuke.Services.FileSystem.FolderMappingInfo.get_ImageUrl() at DotNetNuke.Modules.Admin.FileManager.FileManager.PreloadFolderImages() at DotNetNuke.Modules.Admin.FileManager.FileManager.InitializeTree() at DotNetNuke.Modules.Admin.FileManager.FileManager.OnLoad(EventArgs e) --- End of inner exception stack trace ---

It seems these errors are related.

I'm not sure when these errors starting happening. I have a feeling they were after the last update (which was a pretty big update. I think I updated the site from ver 4 something).

I know there are new updates available, but I am concerned these issues will still be present.

I have a copy of the site (same version) running in a development environment without issues.

Any suggestions would be appreciated.

Thanks,

JM
