Thread:Extension talk:RecentPages/Include RecentPages in Main Page

Sorry for maybe a stupid question, but I'm a newbie with mediawiki. I installed the RecentPages Extension and now I try to include it in the main page by adding the code. The output of the last 6 new pages is correct, however they are not linked but plain text with wikibrackets  like this: [ [ I m the newest page| ] ] What am I doing wrong? Thanks.
