Fix Missing required microformat

Hello,

First of all, thanks for the great theme.

I’m using Yoast SEO plugin. In Search Console i’m getting multiples errors in structured data microformat: “author” and “updated”.

I’ll make the adjustments manually in the theme but it will be a rework whenever I update him. Here the link to the recommendation of the plugin.

Please, if you can adjust this for a future upgrade, I’ll be grateful.
