Sometimes change is unexpected.
Yesterday we had an unfortunate chain reaction of WordPress updates (an auto update forced a manual update, that required a bigger update, …). The end result was our customised theme no longer worked, and the site wouldn’t load. We have things loading again, but… no more theme.
Pamela is working hard to update things. This may be an imperfect process, and we apologise in advance. You may note the <div>s going a bit Picasso along the way, but we will do everything we can to prevent that.
