thx V@no for your reply but it's a bit more complicated.
I've edited the constants.php file to suit invisionboard forum (v1.1.1.) and it works fine. The only problem is the 4images script displaying the wrong number for each group.
In other words:
When a guest visits my website it shows him as a registered user (although he'sand the number of guests is always 0 (Zero).
Did i explain myself correctly
What i'm looking for is the script itself that manages which user types are displayed in each group when showing the stats.
Hope you can point me in the right direction. Maybe sessions.php? or one of the templates?
It's only a cosmetic issue cause the authentification works fine.
btw. i'm sending you a pm to ask a different question about your
C L website.
