I don't see the unit price in the cart, samething for amount of tax and the total that does not appear. I try to change the template but I have the same problem with other template
je ne voit pas les prix unitaire dans le panier, même chose pour le montant de la taxe et le total qui n'apparait pas. j'ai essayer de changer de template mais j'ai le même problème avec les autres templates
have you tried with a standard joomla template?
looks like its a custom template
You seem to have a javascript conflict on your website. Try to disable 'Use external google jQuery library' in VM configuration > Templates tab.
Also - like 'Pro' mentioned already - it looks like you are using an outdated Yagendoo template, which probably is not updated for use with your VM version (looks like it is still using the old jQuery 1.7.1, while the latest Joomla and VM use jQuery 1.11.2. Check if one of the Joomla beez templates works better. With your current template I currently don't even see any 'Add to Cart' button on your product pages.
