Webmaster Tools problem with hatom

Hello, the theme is awesome!!

I’m just having a problem with hatom in Google Webmaster Tools and it seems to be a problem in the theme. For most of the posts and pages the Webmaster Tools says (some of the posts have only 1 or 2 of the warnings):
Missing: entry-title.
Missing: updated.
Missing: author.

I think I’ve found a possible solution for it in these pages:

http://fivera.net/hatom-feed-hatom-entry-error-wordpress-solution/

But I couldn’t find the corresponding tags. Maybe you can help me?

Thanks!!!
