function onCreatureDisappear(cid)           npcHandler:onCreatureDisappear(cid)         end
function onCreatureSay(cid, type, msg)      npcHandler:onCreatureSay(cid, type, msg)    end
function onThink()                          npcHandler:onThink()                        end

local shopModule = ShopModule:new()
npcHandler:addModule(shopModule)

shopModule:addBuyableItem({'cheese'}, 2461, 200, 'cheese')
shopModule:addBuyableItem({'meat'}, 2482, 300, 'meat')

function creatureSayCallback(cid, type, msg)
    if not npcHandler:isFocused(cid) then

Can you please post your addSellableItem and addBuyableItem functions from shopmodule files?

Also, are you sure that it's not a client-side error?

Sorry didnt saw notification.

    function ShopModule:parseSellable(data)
        for item in string.gmatch(data, "[^;]+") do
            local i = 1

            local name = nil
            local itemid = nil
            local cost = nil
            local realName = nil
            local subType = nil

            for temp in string.gmatch(item, "[^,]+") do
                if i == 1 then
                    name = temp
                elseif i == 2 then
                    itemid = tonumber(temp)
                elseif i == 3 then
                    cost = tonumber(temp)

                    local names = {}
                    names[#names + 1] = name
                    self:addBuyableItemContainer(names, container, itemid, cost, subType, realName)
                end
            else
                print("[Warning : " .. Npc():getName() .. "] NpcSystem:", "Parameter(s) missing for item:", name, container, itemid, cost)
            end
        end
    end

Im not sure is it client sided, cant say anything about it.
