I am wondering if anyone has run into this.  I am logged in as the Administrator for our DNN site (v 3.2.2).  I am attempting to edit and save the Stylesheet using the Stylesheet Editor feature found at http://www.<oursite>.com/Admin/SiteSettings/tabid/39/Default.aspx.  I can edit the file displayed (which I believe is actually the portal.css file).  However upon clicking the link to Save Stylesheet, I get an error message saying:

An error has occurred.
Error: Site Settings is currently unavailable.

I looked in the Log Viewer http://www.<oursite>.com/Admin/LogViewer/tabid/48/Default.aspx and find an exception reported that contains the following:

DefaultDataProvider: DotNetNuke.Data.SqlDataProvider, DotNetNuke.SqlDataProvider
InnerException: Invalid File or Directory attributes value.
Message: DotNetNuke.Services.Exceptions.ModuleLoadException: Invalid File or Directory attributes value. ---> System.ArgumentException: Invalid File or Directory attributes value. at System.IO.File.SetAttributes(String path, FileAttributes fileAttributes) at DotNetNuke.Modules.Admin.PortalManagement.SiteSettings.cmdSave_Click(Object sender, EventArgs e) --- End of inner exception stack trace ---

I am not sure where to go with this.  I can add modules and pages w/o a problem so I know the permissions should be correct.  Any help or ideas would be appreciated.  I suppose I could brute force the change by editing the portal.css directly on the file system going around the DNN interface for Admin but I would prefer to know what has happened.

Thanks in advance.
