Are you facing these errors while checking your rich snippets microformat?
Just add these following codes to your respective file and lines:-
For entry title:
[php]<h1 class="entry-title"><?php the_title(); ?></h1>[/php]
For update:
[php]<h2 class="updated"><?php the_date();?></h2>[/php]
For hcard author:
[php]Author:<p class="author"><span><?php the_author(); ?></span></p>[/php]
The above solution is for wordpress, for custom sites, just replace the code with your own code, like the_title will be replace with your page title etc.
Done, now you will see no warnings in testing your webpage on rich snippets testing tool
