I didn't. I went back bed with some strong pain relief.
With the newist neighbour's next door having a young member of the family birthday party, bouncy castle and all. I decided it was the best option. It also stopped the Halloween door trick and treater's calling. Turned out a good day ;o))
Because this happened over the weekend, I have no idea what the cause was. It seemed to be localised on the way the forum pages are served, because I was able to navigate the rest of the site without any problems. I could also access the forum pages via a complex route, but I wasn't able to post.
All seems well now, and as soon as we can discover the cause of the problem we'll update you.
