Wikimedia Bugzilla is closed!

I moved my wiki to new host, upgraded from 1.18.1 to 1.19.0 and now my wikitables can't be aligned via align="" nor style="float: ;" nor style="margin: 1em auto 1em auto"

Here's an example of a template in the old wiki location using align=center :
http://isoset.wikkii.net/wiki/Malline:Taikalaatikosta

Here's the same template with the exact same code on the new host:
http://wiki.isonen.net/wiki/Malline:Taikalaatikosta

Note that in the first example the table is centered as it should, but not in the latter. 

The difference between the two wikis are the MediaWiki version and semantic bundle:
old: http://isoset.wikkii.net/wiki/Toiminnot:Versio
new: http://wiki.isonen.net/wiki/Toiminnot:Versio

The problem occurred with all browsers I tried.
