Members with activity=0 are displayed all on one page in admin panel, although I see pageNav division.

So how much records are displayed? Could you provide a screenshot?

70 names are displayed - same names on all 4 pages.

Yes there is such kind of bug. I will fix it in the next release.

Quick fix: edit bb_admin.php file and locate the comment saying:

/* Determine all disabled users */

there will be a SQL request under it which you need to modify inserting $makeLim after the closing comma and the bracket, like here:

if ($row=db_simpleSelect(0, $Tu, $dbUserId.','.$dbUserSheme['username'][1].','.$dbUserDate.','.$dbUserS heme['user_password'][1].','.$dbUserSheme['user_email']
[1].', '.$dbUserSheme['num_posts']
[1], $dbUserAct, '=', '0', "{$dbUserId} ASC", $makeLim)){
