Conflicting Javascript/jQuery from the Chat Plugin - Any help?

I am seem to be having a problem with the Chat plugin with conflicting javascript/jQuery.

I am unable to open chats and after looking around the internet and wpmudev I have noticed that it is a conflict issue.

Can someone(staff) help me with why the chat isn't working:
