[Mediawiki-l] Unwanted centered text after adding templates

[Sandy Rozhon]

After adding the four required familytree templates as described at 
http://en.wikipedia.org/wiki/Template:Familytree  I now have some odd 
behavior on my WHOLE Wiki in that EVERY page is centered.  I don't 
understand how that can happen as I didn't change the CSS file in any 
way.  How can I fix this problem?  

My understanding of templates is that they are only in effect when 
included on a particular page.  Somehow these templates have altered 
the functioning of all pages.
