Homepage issue

I think long time ago I deleted my page but some pages remained available. Then I wanted to recreate it. Now basically I would need to edit at least homepage but is not working. I am getting only Welcome to Altervista message. In Alterpages I was able to add subpages at least. Tried to convert to AlterBlog but this didnt helped with homepage. Can somebody reset whole page? Or is there any way to recreate it? Sorry for my poor description, any help would be very appreciated! Homepage is http://ombradivino.altervista.org Thanks!

I managed to change the first page showing in Settings/Reading/Static page/I selected a different page, now at least I can edit something:)
