Hi,
– You need to update the theme to the latest version (6.3.6). Never update XStore Core plugin without theme update. Follow this article to update the theme – https://xstore.helpscoutdocs.com/article/63-theme-update
Our changelog you can find here – https://xstore.8theme.com/update-history/
– Then, you can use this plugin https://wordpress.org/plugins/wordpress-database-reset/ ( use with caution, it deletes everything )
Regards, Hung PD
