если было заменено в functions.php
- if ($cur_user['idle'] != '0')
+ if ($cur_user['logged'] < ($now - $forum_config['o_timeout_visit']))
то, даже особо не разбираясь в том как все работает, думаю не лишним поправить ниже
else
{
$query = array(
'UPDATE' => 'online',
'SET' => 'idle=1',
'WHERE' => 'user_id='.$cur_user['user_id']
);
на
else if ($cur_user['idle'] != '1')
{
$query = array(
'UPDATE' => 'online',
'SET' => 'idle=1',
'WHERE' => 'user_id='.$cur_user['user_id']
);
