Thread:Project:Support desk/Multilanguage content not working

MediaWiki 1.18, phpMyAdmin 2.10.1, mysql 5.0.67, Semantic MediaWiki 1.7.1.

http://hafdal.dk/mediawiki/

I have installed the following extensions: Multilang LanguageSelector Polyglot

But I am unable to figure out how to get my pages to be in different languages. I've tried to test the installation with the example given on the multilang page, but it still won't work

@de|"Das ist ein deutscher Text." @en|"This is an English text."

Is there something I am missing? Thanks Rakel
