Hello,
Please update the theme and all required plugins to the latest version.
Before update delete “woocommerce” folder in the directory wp-content/themes/legenda/ and it’ll be reuploaded from a new theme package.
Don’t forget to make backup of the site before update.
Here is video tutorial how to update theme.
