You can make any page of your website the Home (index or start) page with just one click. Simply go Website -> Pages -> click the needed page. Below Properties on the right, tick “Home page” under the field with the name of the page. And that’s it.
When you uncheck the box “Home page” for the current index page, a widget pops us prompting you to select the index page (since the website must have a start page to work properly). Make sure to save all the changes by clicking the “Save” button at the bottom left corner of the interface.
