Edit a page
Once a page has been created, you can edit the page as many times as you like. This could be to update the page title, the back-end layout or to change the visibility of a page.
In the page tree, click the page you would like to edit. Click the edit button which is an icon of a page with a pencil in the bottom corner. When you hover over the icon, it will say Edit page properties.
You will now be able to amend the page properties by going through the various tabs such as General, Appearance and Access.
Please note: Changing the URL segment without a redirect in place could cause broken links if the URL has been used elsewhere or someone has it saved as a bookmark.
Page Appearance
Depending on the setup of your site, you might have multiple page layouts such as Full Width and Page with Button Grid. These can be amended in the Appearance tab.
