The latest theme version is 2.9.
You need update it as shown in our tutorial:
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!
If I delete woocommerce then all my customer data and users would be lost, I just found it best to do it through the Envato Toolkit.
On another note, I installed the new theme and updated the woocomerce plugin and it seems that the variable products are not working. Please advise the status of that. I had to install my back-up to get it to work again but wanted to check the status of a fix on your end.
