Форуми / Cotonti / Support / Internationalization rewrite url problem

Okay, thanks for help. But still i have the problem.

I have a category called "news".

Cotonti displays www.site.com/en/news normally but throws 404 error when I want to navigate to www.site.com/pl/news... how to fix that?

OK, found it. "pl" wasn't in htaccess :)

OK, another thing:

Let's say I have structure extrafield. How to add it to the internationalization? I should edit the internationalization plugin to take this into account?
