Hello @rsangam

That errors comes from WooCommerce version lower than 3.x
Are you using the latest version of SmartBuy theme?
If yes, and you are still seeing this error, you’ll have to contact the theme developer to update their theme for compatibility with the latest version of WooCommerce.

This is how to contact an author on Envato Market:

Hoping it helps a bit,

All the best!
