Issue with active members.

[Stefan118]

In the ACP is an option to display the amount of active members of the last X days.
ACP --> Settings --> Options --> Forum Home Options

Active Members Time Cut-Off

Enter a number of days here that represents a threshold for 'active' members. If a user has visited the board within the past number of days you specify, they are considered 'active'.

Enter '0' to treat all members as 'active'.

It doesn't mather what i enter here, it always displays that i have 77 active members, while my daily login is about 150 to 190 members.

How can i see my active members of lets say the past year?
(If i enter 365 days, it says 77 members, if I say 1 it's also 77 members)
