Problem! Missing: entry title Missing: update Missing: author

Hello:

So I was using google webmasters tools and found out this errors in so many posts:

Error: Missing required field “entry-title”.
Error: Missing required field “updated”.
Error: Missing required hCard “author”.

Ive been looking for the solutions and i found out i have to put this in the code:

1. Add the entry title wherever i find the post title… like in this example…

<h1 class=”post-title entry-title“><?php the_title(); ?></h1>

2. Add an updated word wherever the time word is :S

<time datetime=”<?php the_time(‘o-m-d’) ?>” class=”post-date date updated” pubdate><?php the_time(apply_filters(‘themify_loop_date’, ‘M j, Y’)) ?></time>

and 3. ive to add vcard author words somewhere…

<span class=”vcard author”>
<span class=”fn”><?php the_author_posts_link(); ?></span>
</span>

The thing is that im so noob that i dont really know where, by example the h2 title line ive found no one but some of them one in loop in loop page or in loop single should i add the entry words like this in all of them?

-Originally
<h2 class=”post_title page_title”><?php the_title(); ?></h2>
-correcting??????
<h2 class=”post_title page_title entry-title”><?php the_title(); ?></h2>

Another noob question is entry-title or should i use the _ like this entry_title.

The update thing i found in meta.php this but im not sure if i should put in this piece of code the update word

<?php if(!supernova_options(‘disable-date’)){ ?>
<em class=”meta_date”><?php the_time(‘F jS, Y’) ?>
<?php } ?>

As for the author im even more lost.

help please ??

Thank you!
