I've not knowingly deleted anything. But it is possible. What should there be?
In /home/www there are 54 directories (which are symlinks) called www.hostname.co.uk
or similar, 52 directories called web1 to web 61 with a few missing, one directory called localhost and one symlink called hosting.hairydog.co.uk
However the server is now called www.hdog.co.uk
Could that be the trouble?
