Just below where you checked centerblock there is a drop down that is set to homepage only. Change that to all.
EDIT: Upgrade to the latest version.
Dirk, please tell me why it was set only to 1 page?
If I select more than 1 page, will it affects the security of the site or the server load?
and one more question: could it possible when i set "all" that static page displayed in articles too?
