Hi,
that $locale fi_FI doesn´t work for us. In WP documentation it says that couldsome how work with earlier WP versions. http://codex.wordpress.org/Editing_wp-config.php#Language_and_Language_Directory.
My question is how to use loco with your theme, can you please assist soon, that we will get translation in time. We should open store very soon.
Best Regards
Jan
