I can see that you have used the 'session/cookie' method of implementing a multi-lingual site.
One drawback of this approach (and this is mentioned in the original thread viewtopic.php?p=9010#p9010) is that there would be only a single URL for all languages.
This can have SEO implications as only the first language pages will get indexed by Google (in your case only the FI pages are getting shown).
I think we'll need to do something about this.
Maybe we should add a parameter in the URLs to explicitly show which language is being shown.
Is there anyone who can help out solving this?
