The "Sale" badge disappears from the "Shop" archive page if "toolset" is activated. On the homepage where I've used Kadence blocks to display the latest products the "Sale" badge it appears (hidden link) but on the default archive page it doesn't (hidden link)
Could you have a look and let me know what is wrong? I can set up a staging area for you to test it.
Thank you for contacting us and I'd be happy to assist.
To troubleshoot this, I'll need to see how these two pages are set up in the admin area and it would help if you could share temporary admin login details for the staging website.
Note: Your next reply will be private and it is recommended to make a complete backup copy, before sharing the access details.
I was able to access the website's admin area, thank you.
During troubleshooting, I noticed that the website is not using any Toolset WordPress Archive for WooCommerce shop or product category archive pages, which means that the layout and styles of these archive pages are being controlled by the active theme.
In this case, you don't need to activate the "Toolset WooCommerce Blocks" plugin. Please deactivate this plugin and the "sale" badge will start showing correctly.
