Hello,
Before contacting Woocommerce support (which never answers…), I’d like to be sure it doesn’t come from the theme. I can’t switch the theme to check because the site is live.
On the URL attached, please click on e-boutique, select one bag, the color, add to cart and see the cart. On the right side, you have Subtotal, shipping and global amount. The global amount is not the addition of the 2 others figures. When you decide to pay, everything is back in order.
I ask you because I know your theme add some buttons to woocommerce so you see…
Thanks for your help, Woocommerce drives me crazy.
Nice day!
