@matigo No, but the help is no longer needed.
A bit of a nightmare, but mostly solved now by manually changing the prefix on all the WP tables. I had done some very silly things during the various moves to and from my servers, as a result of which Fornacalia.com vanished into thin air. I still had a backup (which I could not seem to use) and I still had the original SQL database. But when I did a one-click install of WP, it naturally created a new set of tables with a different prefix.
In the end it is all good, except that I don't think I have a copy of all the uploaded media files. That will be harder to restore, but doable, I think.
First I need to search all possible locations for a backup of the uploads folder.
