Hello @mady,
We have installed the Loco Translate plugin on your site, which allows you to edit the language files for the WooCommerce plugin. You can access the language files here: https://slaayshakers.com/wp-admin/admin.php?path=languages%2Fplugins%2Fwoocommerce-fr_FR.po&bundle=woocommerce%2Fwoocommerce.php&domain=woocommerce&page=loco-plugin&action=file-edit.
