Hi there,
You can add the author below the category like this:
add_filter( 'generate_post_author', '__return_false' );
add_filter( 'generate_category_list_output', function( $output ) {
echo $output;
printf( ' <span class="byline">%1$s</span>', // WPCS: XSS ok, sanitization ok.
sprintf( '<span class="author vcard" %5$s>%1$s <a class="url fn n" href="%2$s" title="%3$s" rel="author" itemprop="url"><span class="author-name" itemprop="name">%4$s</span></a></span>',
__( 'by', 'generatepress' ),
esc_url( get_author_posts_url( get_the_author_meta( 'ID' ) ) ),
/* translators: 1: Author name */
esc_attr( sprintf( __( 'View all posts by %s', 'generatepress' ), get_the_author() ) ),
esc_html( get_the_author() ),
generate_get_microdata( 'post-author' )
)
);
} );
The others are possible as well but it’s not possible to add the words before the icons. It would be easiest to replace the icons with the text if that works for you?
