I got the same warning: “Your theme (Classico Child) contains outdated copies of some WooCommerce template files. These files may need updating to ensure they are compatible with the current version of WooCommerce. You can see which files are affected from the system status page. If in doubt, check with the author of the theme.”
Classico Theme bought Mar 14 2018, v.2.1
WooCommerce v.3.3.3
It shows these files outdated in system status page:
classico/woocommerce/single-product/product-image.php version 3.1.0 is out of date. The core version is 3.3.2,
classico/woocommerce/single-product/product-thumbnails.php version 3.1.0 is out of date. The core version is 3.3.2,
Please advise!
