Google Structured Markup Error

Hello!

This is my website: https://www.esigaretten.no/
As you can see it is an online store and not a blog.

When I use google webmaster tools I keep getting errors about my structured markup. It’s missing author, entry-title and updated. I don’t really need this markup on my site since it’s not a blog, but if I remove the hentry code from the templates I’m afraid my rich snippets made by WordPress SEO by Yoast will go away aswell. I believe this because the snippets show up under “Hentry” on google webmaster tools, which is the same place the errors show up. I have not been able to put markup around the author, entry-title or updated to remove the errors either because I use the Venedor theme and my templates look different from all the tutorials I’ve seen around. What should I do about this problem? Will my rich snippets go away if I remove the hentry code?

Thanks!
