"LiveJournal's default layout, the XColibur site scheme, relies on JavaScript ..."
Sadly, XColibur isn't the default anymore. The scheme name needs replacing with Horizon, its flashier upstart nephew.
P.S. A search [http://www.livejournal.com/support/faqsearch.bml?q=XColibur&lang=en_LJ] brings up two other FAQs that probably need similar tweaking?
