Important: changes made in a duplicated Page will not affect the original and vice versa. For example: you create an image gallery in Page A. You then duplicate Page A to create Page B. Updating the Gallery in Page A will not update the Gallery in Page B, and vice versa.
How it works1. Find the Page you wish to duplicate in the Control Panel > Pages tab
2. Highlight the Actions cog and select 'Duplicate Page'
This makes an exact replicate of the page with 'COPY' as a prefix to the name of the duplicated page.
Important: you can change the name of the duplicated page by highlighting the Actions cog and selecting the 'Edit Page Details' option.
