修改  inc/dv_clsmain.php   557行左右，找到

   $ibrowser = sysinfo($_SERVER["HTTP_USER_AGENT"]).'|'.browser($_SERVER["HTTP_USER_AGENT"]);
   $db->query("Insert Into {$dv}online (id,username,userclass,ip,actforip,startime,lastimebk,boardid,browser,stats,usergroupid,actcome,userhidden,userid) Values ('$userid','$userinfo[username]','$userinfo[userclass]','$usertrueip','$seccode','".TIME_NOW."','".TIME_NOW."','$boardid','$ibrowser','$stats','$usergroupid','$actcome','$userhidden','$userid')");
   //$deltime = dateAdd('s',-$fsetting['onlinetimeout']*60,date('Y-m-d H:i:s'));
   $deltime = TIME_NOW - ($fsetting['onlinetimeout'] * 60);
   $db->query("Delete From {$dv}online Where lastimebk<'$deltime'");
  }else{
 下面修改为

   //$reflashtime = datediff("S",$userinfo['lastimebk'],date('Y-m-d H:i:s'));
   $reflashtime = TIME_NOW - $userinfo['lastimebk'];
   $_onlie_time = intval($reflashtime/60);    //此处是计算分钟
   if($_onlie_time > intval($fsetting['onlinetimeout'])){$_onlie_time = intval($fsetting['onlinetimeout']);}  //防止长时间挂机用户
   if(($reflashtime > 120 && $boardid == $userinfo['boardid']) || $boardid != $userinfo['boardid'] || $isupdate == 1){
    $db->query("Update {$dv}online Set lastimebk = '".TIME_NOW."',boardid = '$boardid',stats = '$stats',actforip = '$seccode',usergroupid = '$usergroupid' Where userid = '$userid'");
    $db->query("UPDATE {$dv}user SET user_online=user_online+{$_onlie_time} WHERE userid='{$userid}'");  //此处更新
   }
  }
