If you have made some changes to your site but are not happy with them, or you deleted something you didn’t mean to delete, you can return to a previous version of your site at any time from the History area.
Every time you edit a page, the page saves automatically and a copy is kept for you. To find previous versions of the page, first navigate to the page on your site menu.
Next, select History and you will see a list of the times and dates of all the Page Revisions you have made.
Click Switch to restore a historic version of your page. Don’t worry, you can switch it back at any time.
If you want to restore another page, navigate to that page first.
You can find a snapshot of your website revisions on the Website Manager page. These snapshots are taken every time you open the website builder and you can restore them directly from here.
Please note that the undo and redo buttons are not working optimally. If you have tried them and they do not get you back to the version you were looking for, you have the snapshots to support you.
