Hi,
Thanks for contacting us.
We are so sorry for late response. Because we had a lunar new year one week so we cannot help you. Hopefully, you can understand for us. For your question:
"Woocommerce Products Layouts" is an addon for Visual Composer. -> Your site needs to activate the "Visual Composer" plugin to use this plugin.
After you download the package, you need to unzip -> Plugin -> install "yl_products_layouts.zip".
If not successful, please send me admin your account and link your site (Set as private reply).
I will help you check.
Thanks.
