Multilanguage

Hi,
i’m heaving a problem with this plugin widget and wpml.
My proble is that when i’m in http://www.mydomain.com and apply the filter is correctly redirecting to http://www.mydomain.com/category. But when i visit http://www.mydomain.com/it and apply filter, the plugin redirect me yes to the correct category id but is missing the /it/: http://www.mydomain.com/category-it instead of http://www.mydomain.com/it/caegory-it.

Do you know how to resolve it?

Thanks

G.
