AMP validation Error Google

Hello All,

I just installed AMP plugin.
I can go to
https://breastpumps.byramhealthcare.com/blog/index.php/2017/03/16/how-to-prepare-finances-when-expecting-baby/amp/
and it shows the page.
My following problem is that when I go to AMP Test from google:
https://search.google.com/search-console/amp?id=PWTydXyuJnLviICjDJdSkQ
I get a lot of errors. I’ve been looking possible fixes but nothing solved the problem
I deactivated all my plugins except AMP and go to settings/ permanent links and save but it didn’t solve the problem

Please advice thanks
