I am not able to enter only Sale Price

Hello,

I saw the screenshot you attached.

Unfortunately, there is no option in theme settings to change the behavior of the pricing in products.

The products are controlled by WooCommerce and our theme doesn’t influence this. It is necessary to add the regular price to which the sale price you cannot just enter the sale price without setting the regular price. The sale price must be less than the regular price to make it work.

Please add the regular price greater than the sale price. This will fix the issue.

Best Regards.

In this case, you need to set only a regular price. The sale price has no sense without a regular price.

Kind Regards
