Dear ThemeBrain,
I love your TB Mega Menu, but I have ran into a problem, with a multi-lang site.
Here you can see a working example on the default main-menu:
http://cannabis-social-clubs.eu/
And here you can see a not fully functional example on an additional language menu-main-menu-de for the German content
http://cannabis-social-clubs.eu/de
Please see the screenshots of the Config TB Mega Menu pages.
