You’re using old theme version.
Please update it and you’ll have the options mentioned in the previous post.
Before update delete “woocommerce” folder in the directory wp-content/themes/royal/ 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!
(it’s for Legenda theme but the process is the same).
