It's happened to the bottom bars of the blog page too.
We've checked out other blogger pages and they seem to be all as per normal, which suggests its something that has happened which is unique to our page.
Have we been hacked? Have we been targetted by agencies unknown? Will it ever be restored? Questions we cannot answer as we don't know.
We can only apologise for the inconvenience this glitch has caused ... and please bear with us until the matter is, possibly, resolved. And soon ...
Thanks for your understanding.
