Addon "Freichat" not showing

I have a chattool named "Freichat" installed codologic.com/page/freichat-free-php-chat-script-software

It works on other templates just fine, but I can't get it to work in this template. Do you have an idea how to solve this?

Seems to be a syntax error, see image attached.

Well, that does not ring a bell, but at least I know what to look for. Thank you very much for pointing it out for me
