The welcome messages not updating (or simply changing) was your problem. You were editing a welcome page, but it was showing a different message.

The dollar signs and numbers are variables for the welcome pages which are explained on the Help:Welcome tool page. If they are used correctly, they will not show as numbers in the welcome (and this should be the primary change between what's on the MediaWiki page and the message wall).

Everything works.
