We’d love to help you with your concern however, Woocommerce customizations is beyond the scope of our support as stated in the sidebar of this page.

Thank you for understanding.

Steps to remove sku and or categories from a single product page:
1. Activate or install Jetpack
from jetpack install Custom CSS
2. From your Dashboard Click on Appearance
3. From Appearance choose Edit CSS
A new window will open up:
Edit Themes
CSS Stylesheet Editor
4. copy and paste the following after the last line in the editor – Note: The first three .sku, .posted and .tagged will remove the sku and categories. .product_meta removes both sku and category

.sku {
display: none;
}

.posted_in {
display: none;
}

.tagged_as {
display: none;
}

.product_meta {
display: none;
}

Thanks for the update, we appreciate you hard work to resolve the issue yourself.

You need to use any external plugin to add custom CSS/JS codes, as you can add them via Customizer > Custom CSS.

Have a nice day, Cheers!

(Also tried some variations I found on various blogs about how to remove the SKU.)

Question to Support: Could it be that something in X Theme is overwriting that particular change? And that the approach Jack took — using JetPack — was what made it work for him?

BTW, big thanks to you, Jack, for coming back to post your solution.

Cheers!
