Hi Toader,

1. Why you page doesn't have title? That's weird. I couldn't create a page without title.
2. To be honest using SPPB 4.0.1 for production website is not a good idea, wait for SPPB 4.0.2 at least, and now I suggest to reinstall with SPPB Pro 3.8.8. We have to fix many bugs, so don't waste your energy.
3. In general , after creating a Page - you have to add it to menu, as new menu item to use on front-end view.

where I have to set the margins so that I don't write outside the border as in the picture https://prnt.sc/x_v8ADMsDWRV 2 how do I set the layout height https://prnt.sc/ZvVOlxnowZuK

1. Disable CSS compression in Template Options - I cannot see from where the styles are to help you more. Let me know after
2. About "Home" label - it's page title that you can disable from "Home" menu item settings.
3. For some pages it's better to use Pages than Articles
