is it this one?
You can download the Woojoo theme from here. It is NOT for production, I repeat it is NOT for production.
The theme uses JointsWP 4.0 ( float grid ), I just updated WP to 5.0.1 and WC to the latest version and found no issues. Basically I added what the WooCommerce documentation recommends to make your theme compatible with WooCommerce, that is in the functions.php and a stylesheet ( woojoo.css ) for this style ( nothing special )
