In un file a parte mi funziona, quindi è possibile che l'errore sia in questo .js della chat?
PHP:

var blinkOrder = 0;
var chatboxFocus = new Array();
var newMessages = new Array();
var newMessagesWin = new Array();
var chatBoxes = new Array();
$(document).ready(function(){
originalTitle = document.title;
startChatSession();
$([window, document]).blur(function(){
windowFocus = false;
}).focus(function(){
windowFocus = true;
document.title = originalTitle;
});
});
function restructureChatBoxes() {

} else {

}
