The problems are still apparent on my
website hostings. I did notice the innoDB error message while I was trawling around phpmyadmin - but for much of today the error has been due to missing MYI files - probably related to the problem as a whole. There was a short time when all was fixed - I think that was just after a restart of MySQL server around 5 o'clock, as all MySQL Server
website hostings died for a short time - but quickly the problem returned and all data was lost once more. The error in phpMyAdmin is still due to missing MYI files for the database tables. This problem is not fixed I'm afraid.
