I looked at the tutorials, searched google but couldn't find any relevant info.

Namely:
J! needs to have a default article set for each languge.
I can't see how to do this for K2 items.
If i don't do that, the language selector-flags don't show.

Would someone please show me in the right direction?

Thanks.

PS: re-captcha is awful. Please use a better readable one.

I worked this out thanks.

(For reference: it is a menu-item that needs to be set as a 'home' for a language, not an article/item. IE: in Joomla-menus, nothing to do with K2)

I'm glad you sorted it out.
