Hello,
I know, how the configuration and everything is done. My problem is, if I wanna use i.e. the big featured posts in the Interactive theme, which are configured in the theme options, I have to specify categories. So for the german version of the website, I would need to specify in the theme options the german category names, while I would need to specify the english category names for the english website version. So I would need a language dependent setting in the theme options.
