Hi Jack,
Which version of Genesis are you running? If you’re using the latest version (and also the latest version of Aspire) then the Blog page is set up a bit different. Now it’s recommended to create your Blog Page, title it, and then set it as your Posts page on the “Settings > Reading” page.
Once you go to Settings > Reading in your Admin. “Look for “Your homepage displays” then set it to “A static page”, and finally set your “Posts page” to the Blog page you just created.
Let me know if this helps.
