the problem is;
if you browse website with this URL:
tramax.es/index.php?option=com_virtuemart&view=productdetails&virtuemart_product_id=134&virtuemart_category_id=67&Itemid=475#cart
the "add to cart" works fine, but if you browse the website with this URL:
www.tramax.es/index.php?option=com_virtuemart&view=productdetails&virtuemart_product_id=134&virtuemart_category_id=67&Itemid=475#cart
add-to cart doesn't work.
Open this PHP file:
JOOMLA_ROOT/configuration.php
and make sure $live_site line is empty, like this:
By the way, i strongly believe yours is: public $live_site = '
tramax.es';
Don't enter the live site URL there manually. It will cause the non-www or with-www confusions with Safari and Chrome browsers, because JSON can be made only internally (within the same domain). And Safari and Chrome pretend
www.yourdomain.com and yourdomain.com as separate domains. (it is all about security) Firefox doesn't care about it, on the other hand ;)
Joomla is smart enough to decide what your live site is. So, no need to define live_site manually.
