Every time a page is saved, a copy is stored in QuantumCMS. Using the History screen, you can view previous versions, restore a previous version, or create a Draft from a previous version.
Step 1: You can view the History of any page by clicking the arrow next to the Properties button and selecting “History and Drafts” from the menu.
Step 2: Click on the History tab. You will see a row in the table for each time the page has been saved including the Current Version.
