Help to Show Co-author plus on the frontend

Byline output is usually located in the theme’s inc/template-tags.php, and/or you might see these inside files like single.php and author.php.

If trouble locating the byline output function in your theme, contact the theme author(s) for assistance/instructions for adding Co-Authors Plus

// Display name(s) with no links
if ( function_exists( 'get_coauthors' ) ) {

  // Output display names
  coauthors( null, null, null, null, true );

} else {

  // Replace with your theme's byline code
  the_author();

}

// Display name(s) with links
if ( function_exists( 'coauthors_posts_links' ) ) {

  // Output display names with links.
  coauthors_posts_links( null, null, null, null, true );

} else {

  // Replace with your theme's byline code
  echo '<span class="author vcard"><a class="url fn n" href="' 
       . esc_url( get_author_posts_url( get_the_author_meta( 'ID' ) ) ) . '"
       . title="' . esc_attr( get_the_author_meta( 'display_name' ) ) . '">'
       . get_the_author_meta( 'display_name' ) . '</a></span>';
