We’ve upgraded from IPB 2.1.x to 2.2.1. This is a relatively major upgrade, including a host of changes both up front and behind the scenes. Unfortunately, these means that the skins the board uses are quite broken in some areas, to the point where the board is unusable until these skins are updated. The board will be down while these updates are being carried out. We have no estimate on how long this will take, but we’re working as quickly as possible.
