I have this problem: Error: Missing required field “entry-title”. Error: Missing required field “updated”. Error: Missing required hCard “author”. My single.php code look like this: <?php the_title( '<div class="h1-wrapper"><h1>', '</h1></div>' ); ?> <?php echo get_the_date();?> <?php the_author_posts_link(); ?> How and where do I paste the code to fix the above mentioned problem?
