Spoiler

function onStartup()
db.executeQuery("UPDATE `players` SET `online` = 0 WHERE `world_id` = " .. getConfigValue('worldId') .. ";")
    return true
end

 

Tenta assim:

function onStartup()
db.Query("UPDATE `players` SET `online` = 0 WHERE `world_id` = " .. getConfigValue('worldId') .. ";")
    return true
end
