Thanks for sending over the link. It looks like you need to create the site’s home page. If you’ll look in the theme instructions at https://support.organizedthemes.com/selfie/ there’s a section on the home page that can walk you trough it.
Basically you go to pages in your dashboard and create a new page. Look in the right hand column while making your page and you’ll see a drop-down menu labeled templates. Choose Home from that drop-down menu and publish your page.
Then go to the Settings section in your WordPress dashboard and choose Reading. At the top of this screen you can select what your front page displays. Choose to have a static page as your front page and then select the home page you just published to be your front page. If you’d like to have a blog, you can assign a page for it in the second drop-down there. Then update your settings.
That should bring up the theme’s home page for you with your published home blocks in it. If you have any trouble, let me know.
