[Mediawiki-l] Translation

[ninux (linux)]

Hi,

I've configured my mediawiki in Esperanto, but I've noticed that some 
expressions (eg: navigation, community portal, edit, privacy policy, 
disclaimers, Login required, You have to login to edit this page) still 
appears in English, although they've been translated in the language 
files (LanguageEo.php, MessagesEo.php) and in eo.wikipedia.org.

What's wrong with my installation?

Thanks for any help,

Nino
