http://www.arlo.net/ubb/whoonline.txt here are his directions. the first thing you do is replace the cookie sub in ubb_libray.pl when you do that you actual add 2 extra subs.
WriteUserSession and GetOnlineUsers
since you have an older version of ubb, you had to replace the cookie sub in cookie-lib.pl and add the other 2 subs to ubb_library.pl
you must have added all three subs to cookie-lib.pl. I suppose it would work fine that way. look in your cookie-lib.pl and see if the subs are there by mistake.
