I've just upgraded to the latest version of phpBB which is the forum software that this websites uses. There is a strange issue though that makes the default style not work correctly. The only way to fix it seems to be purge your cache in your browser. You do NOT need to purge your cookies though.
Once that has been done the site should display correctly.
