I am setting up a website, and the web and mobile options are already configured. Now I'm trying to configure the tablet view, but when I did that I got three errors, the same ones, that I don't know how to solve. Has anyone already experienced this and could tell me how to solve them?
You have configured default home page but I think you missed to configure Role-based home pages.
I think you need to configure home page for each role.
Just click on edit button which is front of role-based home pages and select target page for each role.
