Thanks - I've uploaded the files again however when I click on Tools -> Database Backup all I see is as follows (no backup button):

Database Backup Manager - MySQL
Title Date Size Action Backup

Directory: /usr/local/psa/home/vhosts/iamhappie.com/httpdocs/admin/backups/
RESTORE BUTTON

Any thing else I could try? DrByte? There are a few others who have had the same problem without a resolution. Thanks as ever!
