The server that this website runs on has just had a major OS upgrade, and has also just changed from 32-bit to 64-bit at the same time. This took the better part of a day to debug and poke into working. There may still be some rusty bits that fall over if poked too hard.
One annoyance I have right now is that my old wordpress theme has been declared unworthy and is no longer offered. I have a choice of three themes, no one which seem to put a side-bar up, all links are relegated to the footer – probably so things look good on mobile.
