qTranslate conflict

Hi.
I’m setting up a new WP site (http://www.spotapp.mobi) and I’m trying to use wp-appbox (2.3.2) with qTranslate (2.5.38) and slug (1.1.5), but I’m having a bad time.
When the qTranslate plugin is enabled, the wp-appbox stay always in its default language, germany.
Is there some suggestion on why this is happening and how can I fix it?

Thank you.
