Hello everyone, when I go to any npc and type something my server prints this error:
(further down you see the part of npcsystem/modules.lua that is refered to)

Code: 
attempt to index a function value
stack traceback:
    [C]: in function 'getSpectators'
    data/npc/scripts/lib/npcsystem/modules.lua:275: in function <data/npc/scripts/lib/npcsystem/modules.lua:272>

    data/npc/scripts/spellsfree.lua:8: in function <data/npc/scripts/spellsfree.lua:8>

Here the modules.lua
Code: 
        -- Custom message matching callback function for greeting messages.
        function FocusModule.messageMatcher(keywords, message)
                local spectators = Game.getSpectators(getCreaturePosition(getNpcId()), false, false, 0, 7, 0, 7)
                for i, word in pairs(keywords) do
                        if(type(word) == 'string') then
                                if(string.find(message, word) and not string.find(message, '[%w+]' .. word) and not string.find(message, word .. '[%w+]')) then
                                        if(string.find(message, getCreatureName(getNpcId()))) then
                                                return true
                                        end

                                        for i, uid in ipairs(spectators) do
                                                if(string.find(message, getCreatureName(uid))) then
                                                        return false
                                                end
                                        end

                                        return true
                                end
                        end
                end

                return false
        end

othire distro / edited / npc's yet untouched - only added advanced jiddo npc system (module)
(needed the advanced because regular othire was missing sellspell stuff for example)

I tried a few things but I can't really understand the misstake or I simply don't see it so I am kinda helpless when it comes to making up possible solutions

Okay I saw something in my spellsfree.lua which I removed (marked red)
Code: 
local keywordHandler = KeywordHandler:new()
local npcHandler = NpcHandler:new(keywordHandler)
NpcSystem.parseParameters(npcHandler)
function onCreatureAppear(cid)                npcHandler:onCreatureAppear(cid) end
function onCreatureDisappear(cid)             npcHandler:onCreatureDisappear(cid) end
function onCreatureSay(cid, type, msg)        npcHandler:onCreatureSay(cid, type, msg) end
function onThink()                            npcHandler:onThink() end
local node1 = keywordHandler:addKeyword({'find person'}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, text = 'Would you like to learn find person for 80 gp?'})
    node1:addChildKeyword({'yes'}, StdModule.learnSpell, {npcHandler = npcHandler, premium = false, spellName = 'find person', vocation = {1, 5} , price = 80, level = 8})
    node1:addChildKeyword({'no'}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, text = 'Cant you handle the power of the spell?', reset = true})
local node2 = keywordHandler:addKeyword({'light'}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, text = 'Would you like to learn light for 100 gp?'})
    node2:addChildKeyword({'yes'}, StdModule.learnSpell, {npcHandler = npcHandler, premium = false, spellName = 'light', vocation = {1, 5} , price = 100, level = 8})
    node2:addChildKeyword({'no'}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, text = 'Cant you handle the power of the spell?', reset = true})
local node3 = keywordHandler:addKeyword({'light healing'}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, text = 'Would you like to learn light healing for 170 gp?'})
    node3:addChildKeyword({'yes'}, StdModule.learnSpell, {npcHandler = npcHandler, premium = false, spellName = 'light healing', vocation = {1, 5} , price = 170, level = 8})
    node3:addChildKeyword({'no'}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, text = 'Cant you handle the power of the spell?', reset = true})
npcHandler:addModule(FocusModule:new())

But now leaves me with this error:
Code: 
attempt to call a nil value
stack traceback:

Something is wrong with your npc system its not creating the keywordhandler, you probably made something wrong when adding this "jiddo npc system" or it doesnt work.

Well yea I think the same, but it seems there are no more ressources and stuff for that, must be too outdated...
