I am facing with the problem of creating a backup of dataform.
The following error occurs:
Fatal error: Class 'backup_dataform_activity_task' not found in /home/mzone/m-zone.study/backup/util/factories/backup_factory.class.php on line 107
I am using Moodle 3.0.7 and Dataform 3.
Is there any idea what cause this problem and how to fix it. Thank you.
