Pages - Editing page path and title
The path is part of the page's URL. For example the Gallery page will be created at yourname.com/gallery/ by default. If you want to change this, you don't need to recreate the entire page, you can just change the path and title.
To edit the path, go to the relevant page and click the Edit button. Click on the Details tab and make your changes to the Path and Page title fields. Click Update.
Changing the path will break any navigation links pointing to the old page. Make sure you update your navigation items after you make changes.
