I do not have access via FTP currently but I seem to remember the main theme is Fusion, which also includes an editor and a few other things.
Thanks for the response Lisa.
Unfortunately I can not remember the name of the theme as I inherited the site & being unable to log in I can not find out but when I can get back in I will see if it is the culprit.
The webhosting vendor have rebuilt the database but I will check out the info on backing up the site on the link.
