Products Not Visible on Sale Page

Test it with default WP theme and make sure you have some products on sale.

We tried it on the default WP theme. Still it does not work.

Have you tried it on clean WP with only Woocommerce, demo Woocommerce data and our plugin?

Here is demo https://wpgenie.org/woocommerce-drop-prices/on-sale/

It is working fine on another blank website.
How doi figure out whats the problem on my website (EmiaratesCubeShop.com)

Is it possible that your plugin might be clashing on another plugin which I have it on my website?
