Thread:Project:Current issues/Infobox not working

Hi - I am having no end of problems with my infobox's in MediaWiki 1.21.1. So far I have: updated Parser Functions; updated Scribuntos; copied the Wiki Template:infobox into my wiki. Still the box doesnt appear, and now all content is on the right. See here: http://www.modelhorsepedigrees.com/wiki/index.php?title=Blank_model

I really need help. They once worked, long ago, but now nothing. The template links are:

http://www.modelhorsepedigrees.com/wiki/index.php?title=Template:Infobox_racehorse http://www.modelhorsepedigrees.com/wiki/index.php?title=Template:Infobox

This is driving me nuts. I've had others look at it, but no one can see what is wrong. Any ideas? I've stripped out content in my last ditch attempt to get things to work.
