Wikia doesn't keep chat logs anywhere. However, one of the users here can make a bot that records what's said in chat. See this for details. There are some requirements and you gotta read the entire blog post but I think this is just what you're looking for assuming you meet the requirements. I'd advise you think very hard about getting this though. My wiki decided against it because it can seriously diminish chat's value as a social tool when users know someone's always watching and recording. My experience is that the users there know what happened and screenshots are an option. But if your wiki wants it it's there. I don't know how it works so you would have to ask someone else about that.
