What the chat page has to do - is load the header of the page in an IFRAME which contains the "send header" function. This part of the page refreshes every 9 minutes (or else the user drops off the Who's Online list after 10 minutes of not reloading any pages).
Then the middle of the page is another IFrame containing the chatmodule and the footer of the page.
So for this to work right, you need to turn off the sidebar on the chat page.
If you're using the IIP sidebar mod posted here - you can disable the sidebar on specific pages by placing:
$config['iip_call'] = 1;
above the send_header function on the page you don't want the sidebar.
If this doesn't work for you - you might be able to adapt the RaiderSoft stuff to this older chat mod that Dalantech and I worked on.
https://www.ubbdev.com/forum/showthreaded.php?Cat=0&Number=64465It uses a regular page - so the sidebar will work fine. But instead of being able to refresh the header, it uses a little popup window which pops under the chat page, and refreshes every 9 minutes to update the who's online page.
But it's an old mod and was written for Jpilot.... but you could probably easily inert the Raidersoft chat code in instead.
