Typed text not appearing in chat room

[Merlo]

Hi,

I have used Ajax Chat for years on my website. I've just moved my website to a new host and since setting up the chat room I have a problem...

The chat room loads fine and people are able to log in and appear in the online list. But nothing we type appears in the main chat window.

I'm sure it's probably something I've missed when migrating to new host. Any ideas?

Thanks
