Countdown Timer not showing on For Sale Products

I presume you’re using a plugin for the countdown, is that right?
If so, it’d be best to contact the plugin author, as this isn’t a direct issue with WooCommerce Core.

What you could do to troubleshoot though is check the web console to see if there’s any JavaScript errors which would hint to some plugin conflict.

It’d also be good to run through this troubleshooting guide: https://docs.woocommerce.com/document/woocommerce-self-service-guide/

We haven’t heard back from you in a while, so I’m going to mark this as resolved. If you have any further questions, you can start a new thread.
