Hello,
1. Please update the theme to the latest version and Woocommerce as well.
Before update delete “woocommerce” folder in the directory wp-content/themes/legenda/ 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!
2. Please try to use this Products element http://storage3.static.itmages.com/i/15/0528/h_1432804918_1753641_e35f162b63.png instead of Product Category element of Woocommerce.
Thank you.
Regards,
Eva Kemp.
