Most StudioPress themes use a widgetized home page. This means that the standard WordPress blog page is missing and you have to make your own blog listing page.
This is easy!
First make a new web PAGE called blog or articles etc.
In the WordPress page editor screen go to, Page Attributes and choose a Template type of Blog.
Then, so your site visitors can find your blog page. Add a link to this new blog listing page to your navigation bar
For more advanced settings. In the dashboard go to…
Genesis → Theme Settings. Then scroll down to the sections labeled Content Archives & Blog Page Template. Adjust the settings to suit your needs.
If you can’t see the page attributes box…
In screen options make sure Page Attributes is ticked & visible.
