Hello @Inesita,
The settings for the Blog page can be found in the Theme Options > Blog > Blog Layout.
The free version of Elementor which comes bundled with our theme doesn’t allow editing the default posts page – Blog.
You can create a custom page, edit it using Elementor, then add this page to the menu with the custom title “Blog”. Content of this custom page can be created using one of our elements, for example – https://xstore.8theme.com/elementor/demos/minimal-fashion02/posts-element/ – https://xstore.8theme.com/elementor/demos/minimal-fashion02/posts-chess-element/ , and this custom page can be edited using Elementor.
Best Regards,
8Themes Team
