TriggerServerEvent error on Linux

[Erknneto]

Hi guys.. I have a problem in a Linux DayZ MTA Server. If happens everytime when a serverEvent is called...

Error: Error: Client (Juquinha) triggered serverside event onPlayerChangeSkin, but event is not marked as remotly triggerable

Code:

client side

elseif itemInfo == "Put clothes on" then 
        triggerServerEvent("onPlayerChangeSkin",getLocalPlayer(),itemName) 

server side

function addPlayerSkin (skin) 
    local current = getElementData(source,"skin") 
    local name = getSkinNameFromID(current) 
    setElementData(source,name,getElementData(source,name)+1) 
    setElementData(source,skin,getElementData(source,skin)-1) 
    local id = getSkinIDFromName(skin) 
    setElementData(source,"skin",id) 
    setPedSkin(source,id) 
    triggerClientEvent(source,"refreshInventoryManual",source) 
end 
addEvent("onPlayerChangeSkin",true) 
addEventHandler("onPlayerChangeSkin",getRootElement(),addPlayerSkin) 

Can someone help me to solve this problem? I happens only in the linux server.

There is another addEvent call with "onPlayerChangeSkin" somewhere that is missing the 'true'
