"Warning: Missing required field entry title" in Clean Retina theme

Okay, so bear with me on this one since i’m very new to all this. With Google Webmaster tools I tested my Structured data and got these 2 warnings.

Warning: Missing required field “updated”.
Warning: Missing required hCard “author”.

Obviously I googled the problems and found a lot of people recommending changing the code on the single.php file of my theme where you should alter these 2 lines:

<?php echo get_the_date(); ?>

<?php the_author(); ?>

However on Clean Retina this original coding doesn’t exist on the single.php file or any other file i’ve looked at, i’ve also searched the Clean Retina supported functions page for these and found nothing.

The site is below if it makes any difference.

Thanks a lot for any help 🙂
