Wordpress/Woocommerce post was called incorrectly - php

Question

I fixed all woocommerce deprecated functions except one,maybe someone can help me out.I am no professional. Thank You.
The only plugin activated is woocommerce so there is no plugin conflict problem.The wordpress is up to date so is woocommerce.
I am getting this notice,and from what I see the problem comes from page.php.
