Hi Ken,
I wanted to get back to you on this but for a variety of reasons I was not able to test out your suggestion until this weekend. We checked that the file was there and the permissions were set to 0755. And it hasn't helped. When a certificate is installed in a course, I cannot backup the course. Once I delete the certificate from the course then I can backup the course. I am going to try replacing the file backup_certificate_activity_task.class.php from the zip download for that version of the certificate and if that doesn't work then uninstall the certificate and re-install the most recent version of the certificate.
Thanks for your suggestions.
Dan
