Hello,
As I see you are using old theme and required plugins. Please update them to the latest versions.
Before update delete “woocommerce” folder in the directory wp-content/themes/legenda/ and it’ll be reuploaded from a new theme package.
All required plugins can be downloaded here https://www.8theme.com/download-plugins/ .
Don’t forget to create back up of your files and database before starting update process!
Regards,
Jack Richardson.
