The blog is back and live this morning.
You will note there is a problem with the font set for some strange reason. That's still being worked on - and no doubt will be solved in due course. In the meantimes offers as to reasons are gratefully received.
But that apart I think all is functioning again on the latest version of WordPress.
And the link between here and my Twitter feed is now live - and an important part of the whole blog for the future.
Thanks again to Clark Gascoigne for his sterling efforts.
