Cross Apple Theme

Hi,

I am helping someone build their WP site and it is using a theme I have never come across before – ‘cross apple’. Anyway, we made his first post https://mybusiness-site-income.com/eliminate-computer-viruses-forever/
But if you go on the home page its just blank.
I think its supposed ot have fancy sliders on it.
Can anyone please tell me how we get some content on the home page? He is no loger in contact with his designer and he does not have any instructions for his theme.
Thanks a lot.
