Thread:Extension talk:Cite/Cite does not create references

MediaWiki: 1.19.2 Snapshot of the Cite: for MediaWiki 1.19.x

So, I installed the Cite and added require_once to LocalSettings.php

Now I'm trying to repeat the example: According to scientists, the Sun is pretty big. The Moon, however, is not so big. == Notes ==

and I get the folowing: According to scientists, the Sun is pretty big. The Moon, however, is not so big. Notes  

What's wrong?
