Strange issue with no. of active users
 

I mvoed my forums to vbulletin from myBB like a month ago. Now what happens is, i have more than 1k users, everytime a new user is added, the number of active user is subtracted from the number. i.e. yesterday it was 320, now it is 294.... what cud be the issue?

Thanks.

Have you tried updating your counters and rebuilding the appropriate information?

Admin CP >> Maintenance >> Update Counters

did that but didnt help.

Active Users are defined as "A member is considered 'active' if they have visited the board within the number of days specified in 'Active Members Time Cut-Off'." So, that number will be changing all the time based on the time cut-off.

Oh, Active Members. I thought you were referring to member count. Yes, Active Members is, of course, a fluid number.

but i know that i am not loosing on active members, but why the number keeps going down and down with new registrations?

Try disabling your modifications and see if this still happens.
Note: To temporarily disable the plugin system, edit config.php and add this line right under <?php
