After I've updated to 1.2.2 I can't access the category pages anymore, e.g. when I try to load http://www.domain.com/shop/product-category/something/ I get an 404 error.
What I also experienced is, that the slug of the german version is written with uppercase letters, e.g. domain.com/shop/Produkt-Kategorie/something. That is totally unusual and looks like crap! Please change that.
