This is one of the easier steps of configuration. All you need to do is create a page that will be your default posts index page. (or blog page) You don’t necessarily even have to do this if you create your own using a Page Builder custom template or something like that.
This page uses the default index.php within the Cortex theme installation file should you want to customize that output with a child theme.
- Create a page, or pick an existing news/blog template page
- Navigate to Settings > Reading
- In the drop down, select the page you just created. This page’s content is ignored.
- Hit Save Changes and that’s it
