Please read our documentation http://www.8theme.com/demo/docs/legenda/#!/installation_upgradehttps://www.8theme.com/download-plugins/ (https://www.8theme.com/faq/ – How to update plugins included in theme?).
Before uploading theme files delete “woocommerce” folder, which is located in wp-content/themes/legenda/ to avoid problems with old files (it’ll be reuploaded from a new theme package).
If you made changes in template files, transfer them into the child theme, to prevent losing it after theme update. Also, check the widgets and make sure that you know where every widget is placed because they could be messed up after the update. Don’t forget to create backup of your files and database before starting update process!
You need to enter your purchase code to activate the theme and skip Setup Wizard.
