When I try logging into http://url:8080/manage it shows the view of index_html in the main frame instead of the management area.  If I try clicking on any other folders, besides Quickstart and Control_Panel, nothing happens--the view of index_html just remains in the main frame. 
    I have tried logging out and logging back in with every user, but I get the same result.  I've also tried stopping and restarting the zope server.
    Any ideas why this is happening, or how I can correct it? 
 
    Thanks
