webalizer stats directory is forbidden

I get this error when trying to access the webalizer reports directory. This module was enabled with the template, but I disabled it for a time. Now I re-enabled it via the [Edit Virtual Server] page, but I still cannot login. The directory is there, but there is no prompt via the browser for a username/password as before.

"You don't have permission to access /stats/ on this server."

How can I re-enable this function?
