UBB.Developers Forums UBB.classic V6 Mod Questions oh no what a damn bug

gee
i need help here guys
i've installed force login hack posted at database and there's a very naughty bug
unreg users can see all non private forums threads
lets say a user points to http://blahblah/ubb/NonCGI/Forum2/HTML/000001.html directly
damn Guests can see entire threads, entire forums contents....
is there any way to protect HTML dir?
can i make non private forums dir like in private forums?random dirs?

I don't think a login hack prevents guests from seeing topics...

You can try something like checking for a Username stored in a cookie.

This can also be done in Javascript. If you insert this piece of code in the header it will check if a user has a username stored and if not you can close the thread or redirect them to the main screen.
