More of a suggestion than a bug fix. I noticed that by default you comment out the following line in config.php:

$conf['demomode']=true;

I would suggest that you don't comment the line, but rather leave it intact like this:

$conf['demomode']=false;

I suggest this because a default installation spits out error messages when the entire setting is commented out. I logged in for the first time and immediately changed the root admin password, only to see this error:

Notice: Undefined index: demomode in /home/brian/public_html/livechat/class/operator.php on line 257

It appears operator.php is looking for that setting and errors when it's commented out.

Just a small suggestion. Thanks for all your work.
