I’m trying to update the theme to 3.1 because Woo Commerce has completely broken by site, how can I do this? Is there a simple how-to on how to update the theme without losing all my settings?
To update the theme you need to download the latest version on ThemeForest -> Downloads. Then just reupload new theme via Appearance -> Themes but install this plugin firstly https://wordpress.org/plugins/easy-theme-and-plugin-upgrades/
Also, we suggest you make a backup of all your files before any update.
