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:

^ above is the link of where the chat is held; I will need to supply site login and WP login to a staff member, but would heavily appreciate if someone could look and help me with this issue.
