Hi,

I follow this guide

https://www.commercegurus.com/docs/shoptimizer-theme/adding-an-additional-product-tab/

But i dont have a second tab on my product page.

I tried, to desactivate all my plugin and my theme but its the same.

I follow https://docs.yithemes.com/yith-woocommerce-tab-manager/ too.

I just need to create a tab and click “Enable Tab” in backend ?

I dont understand why that dont work

I use siteground, php 7.3 on staging
