To create a post, navigate to “WP-admin > Posts > Add new”.
Default WordPress Editor
Here you can:
- specify a link for the “Back” button (more info is available here), different to the one pointed in Theme Options -> Post Types;
- hide featured image on a single post page (in other words, inside of an individual post);
- select categories for related posts (fig. 2):
- post preview width on a blog page (normal or wide) is not applicable when using Elementor Posts Masonry & Grid widget – you can disregard it.
“About the Author” (fig. 3) information comes from Dashboard -> Users -> [open appropriate profile] (fig. 4).
For the author avatar you should be registered in the web-site (Dashboard -> Users -> Your profile) using the same email address, as at Gravatar.com.
