When the page comes up it just says, "plug-in not supported".....I know it will be something straight forward but any advise is welcome please and indeed thank you..!!
Had the same problem. If you're using chrome, you need to enable the plug in. On the Java website they address the issue and walk you through the solution.
I think the Java update is the problem. I was able to access the chat room before the update on Safari, but after updating I can't anymore. Chat didn't work with Chrome before or after the update.
We are working on a long term fix for this issue, as it is one that lies with the chat server people. Until that happens all we can advise is to keep trying various different browsers until one works.
