Customize the post meta to work wo Co-Authors plus plugin

Activate a child theme

The first step in adding integration of the Co-Authors Plus plugin to Divi, is to have a properly configured child theme active to your server.

You can download a proper child theme, from this https://github.com/eduard-ungureanu/Divi-Child-Theme

Implementing the changes

1. in your Child Theme folder open and edit the functions.php file
2. add this code to functions.php file

function et_pb_get_the_author_posts_link(){
	global $authordata, $post;

	// Fallback for preview
	if ( empty( $authordata ) && isset( $post->post_author ) ) {
		$authordata = get_userdata( $post->post_author );
	}

	// If $authordata is empty, don't continue
	if ( empty( $authordata ) ) {
		return;
	}
	if ( function_exists( 'coauthors_posts_links' ) ) {
		$link = sprintf(
			'<a href="%1$s" title="%2$s" rel="author">%3$s</a>',
			esc_url( get_author_posts_url( $authordata->ID, $authordata->user_nicename ) ),
			esc_attr( sprintf( __( 'Posts by %s', 'et_builder' ), get_the_author() ) ),
			coauthors_posts_links( null, null, null, null, false )
			);
	} else {
		$link = sprintf(
			'<a href="%1$s" title="%2$s" rel="author">%3$s</a>',
			esc_url( get_author_posts_url( $authordata->ID, $authordata->user_nicename ) ),
			esc_attr( sprintf( __( 'Posts by %s', 'et_builder' ), get_the_author() ) ),
			get_the_author()
			);
	}
	return apply_filters( 'the_author_posts_link', $link );
}

3. make sure you clear your browser and server cache

Note: Since we have changed the default Divi function that display the author this change will be also reflecting on the Blog module, Post Title, Post Slider, etc
