Hello,
I have downloaded from Themeforest the theme, and I can see in changelog.rtf this:
2012 08 09 - Version 1.8
FIles that changed:
Style.css - updated version number
folder: framework - update to the latest version
woocommerce:
woocommerce-config/woocommerce-mod.css
But then, when I check the style.css file I can see version 1.7.
Can you please confirm that last version is uploaded in ThemeForest, please?
Thank you!!!
