Hello @irmankarim,
As I see you are using old theme version. The latest version is 1.8.
Please update the theme and required plugins to the latest versions https://www.8theme.com/download-plugins/ .
Before update delete “woocommerce” folder in the directory wp-content/themes/theleader/ and it’ll be reuploaded from a new theme package.
Don’t forget to create back up of your files and database before starting update process!
Best regards,
Jack Richardson.
