Upgrading Moodle database from version 1.9.17 (Build: 20120312) (2007101591.12) to 1.9.19 (Build: 20120706) (2007101592)...
Your Moodle files have been changed, and you are about to automatically upgrade your server to this version:
1.9.19 (Build: 20120706) (2007101592)
Once you do this you can not go back again.
Please note that this process can take a long time.
Are you sure you want to upgrade this server to this version?
