I figured it out, it was me. The forum is behind an htaccess authentication, for the setup etc. It seems like this plugin goes and literally uses a web access to the showthread url for this, so, if a general user without anything special cant see it (say user and password, or even if you would block the printthread for non registered users) it would not work anymore.
It is a great plugin and i keep it in, but you should note that in the first posts text, so it is very clear what it does (direct http access).
