Please update the theme to the latest version 3.0.3.
Before update delete “woocommerce” folder in the directory wp-content/themes/legenda/ and it’ll be reuploaded from a new theme package.
Also update all required plugins http://www.8theme.com/download-plugins/ .
Don’t forget to create back up of your files and database before starting update process!
Did the updates and still not working. My developer has to override the themes functions to add the “add to cart” button on the single product Oage and the 3 column product page. How do we add it naturally through the theme.
