Before update delete “woocommerce” folder in the directory wp-content/themes/theleader/ and it’ll be reuploaded from a new theme package.
Also update all required plugins https://www.8theme.com/download-plugins/ .
Don’t forget to create back up of your files and database before starting update process! https://www.youtube.com/watch?v=KdWESIIPU1k
(it’s for Legenda theme but the process is the same).
