You may need to add support for a WordPress Custom Post Type after the post type has been registered, eg where a plugin or theme introduces new post types without all the required support.
You can do this using the function add_post_type_support().
Add Post Type Support to Custom Post Type
Code
For example, to add author support to the post type
example_cpt, add the following code in your child theme functions.php:
add_post_type_support( 'example_cpt', 'author' );
