Looks like you forgot my guild chat plug in. That creates the chat3 frame and places it inside the infopanel to the right. Unfortunately without it loaded I can't tell the chat frame what to do. So to solve your problem just download the nUI : InfoPanel [GuildChat] plugin from the nUI Plugin downloads page or move the frame over to the normal chat frame and re-dock it. It should still keep its initial guild only chat channels but shouldn't be any different from the normal chat frames otherwise.
However, my brother gave me an idea on how I might be able to get around the ability to tell the chat frame to dock itself on the left if the addon isn't available to use it on the right but not sure when I will get the opportunity to try it to see if it's possible.
