Hello @restaurant-ruble,

The Restaurantz pro theme uses the site origin’s page builder layout for the site setup as in the demo of the site.

Please make sure you have installed and activated all the theme recommended plugins and have set “A static page” option in Admin Dashboard > General > Reading > Front page displays option.

After setting your front page, edit the page using site origins page builder and insert the theme defined Home page layout in the editor.

Save your changes and you will get the layout in the front page.

If you require any help further, please let us know.

Hope this Helps,

Best Regards !!
