Missing: author and Missing: updated

Dont mind anymore, I have fixed this issue.

The solution:
Open the functions.php file, search:
<span class="entry-date">
then replace with:
<span class="entry-date updated">

continue search
<span class="entry-author-link><?php the_author_posts_link(); ?></span>
then replace with:
<span class="entry-author-link vcard author"><span class="fn"><?php the_author_posts_link(); ?></span></span>

Thank you! This fixed the problem on my blog articles. But on the pages throughout the site, I’m still getting the error. Any idea why?

I can not find any function in this theme which generates those classes.
I will update the topic when I have my solution.
