As you probably remember the last software update I did ended up with a load of problems, (some of which I still haven't fixed yet!)
It looks like that this was due to the theme we are using here on the forum. Basically it is no longer being updated so as the core files move on, we could get to the point where the theme doesn't work at all.
As a result I am looking at bringing a new up to date theme on line. I have created a test forum and have started to suss things out - but it will take a little time.
The main reason for telling you is if the site is unavailable, it is probably to do with me moving things around - although that won't be in the next couple of weeks.
