I would have thought that a shopping cart is to do with WooCommerce, rather than a theme? anyway, the theme is the latest version (1.7.5) at least I assume its the latest version.
Is there a php file I should be checking?
ps. – I took maintenance of this site over from the previous designer, who purchased the theme originally. I cannot access / submit questions to the Woothemes support desk from my account… very bloody frustrating!!
