I have default site in english and option to use Spanish. All the cart changes to Spanish and product listings ok. Lastest joomla 3.4.3 and VM 3.0.9
When I add a product to cart the pop up comes up with Continue shopping, Show cart and 1 x product was added to your cart.
I have used overrides to change the words to Spanish but popup continues to display in English and shows English cart if selected. If I add to menu a link to vm cart it displays in Spanish ok.
Why wont this box come up in Spanish ?
Usually that is a Joomla language switcher/router problem. VM 3.0.9 was tested with Joomla 3.4.1 and afterwards things changed again in Joomla. Try to update to Joomla 3.4.4 and VM 3.0.9.4 or later from here: http://dev.virtuemart.net/projects/virtuemart/files
