Perhaps my explanation has not been good.
If you go to the home page, you can see the content is only a grey background and the word “Inicio”. You can see on http://sjvabogados.comprardominio.eu/ or on https://prnt.sc/zlb6dc
When login login to backoffice with credentials provided, you can see on menu item “Home” , that it has asigned (as Default page), the SPPage Id=1, can see it on https://prnt.sc/zlc2k2
If you go to SP Page Builder, and click on page Home (It is the Page Id= 1, see https://prnt.sc/zlcc2h), you can verify that this page has several rows and addons: Slideshow, Heading, Image, Txt Block.. https://prnt.sc/zlcnrj They are not shown on home, instead of it, it shows the mentioned word “Inicio”.
Also something very strange.. On same screen, when you are editing page Home, from the backoffice, if you click on Frontend Editor or in Preview, it doesn´t show this content, it shows another one, the word “inicio” and the content of Article ID=1. Also, without the options to edit at frontpage.
