When editing a unit in a course you might need to roll back to some older version of the it. eFrontPro keeps track of modifications you make on your content and gives the option to access older versions and even roll back to them.When logged in as administrator or instructor (or any other user type that has privileges to add/edit content) visit the content you want to edit. You can do this by the course's dashboard where a list of all course units are displayed and click on the unit you want (1).
When accessing the unit and if there are any older revisions of it (meaning that you have not just created the unit), an option to view all older version of the unit will be available next to the edit button (2).
Clicking on this button will open a dropdown menu with all older revisions of the unit you are currently editing (3). Clicking on some older version of the unit will preview that older version will all contents of the unit at the time. You may choose to revert back to that version by clicking on the corresponding option (4).
