URGENT: New version hide “Add to Cart” button on my ecommerce site

I recently create a new eccommerce website. Of a sudden, I discovered that the “Add to Cart” button was not visible. Instead, it wrote “View Product”. I deactivate most of my plugins and reactivate one after the other to discovered which one is causing the problem, of which I later found out that it’s the Redux plugin. I’ve updated and also back-dated the Redux plugin, but it’s still not working. I use Electro theme. My website is https://pcplaceng.com. Please help, it’s urgent.
