So, i am trying to implement rich snippets for my site on the search engines for some SEO shit. But on Google's strutured data testing tools (on the extracted structured data: hatom-feed section) i keep getting two errors on every page:

Error: Missing required field "updated".
Error: Missing required hCard "author".

I have changed the theme's single.php file with the correct replacements as suggested by numerous sites. On the structure data testing tool's preview however, the same errors are showing up.

I only updated the single.php files one hour ago, does it take quite a long time to update or is it something I did wrong?
