How to remove hentry errors appearing in Google Webmaster Tools for my WordPress

On which page?

On each page of the website

my website: https://www.mycuistot.fr

Authors and dates only appear on posts. Not on static pages.

So, how should I deal with this Google error, not good for my SEO.
I don’t have this problem with you other theme:
https://blog.mycuistot.fr

Thanks a lot for your help

Your blog has authors and dates because you are using posts.

Pages do not have this information since they are static and the publishing date and author are not considered to be important. Most themes do not include this information on static pages.
