WordPress Chat in Blog Page Corner

The plugin has been activated across the test network. The first blog is a mirror image of our utilized site. We have a additional blog on our Test Server for testing called "Test Blog". On the main blog, the chat functions in the right hand corner as it should, but when I switch over to the Test Blog, the chat option in the lower right corner. When you click to maximize it for utilization, it fails to do anything. Any ideas why or solutions?
