Hello,
1) Follow the multivendor plugin documentation to remove that tab https://wc-marketplace.com/faq/how-to-remove-more-offers-tab-in-the-single-product-page/ It’s not our theme tab
2) To translate Shopping cart text make sure that you synced the XStore theme and XStore Core plugin translation https://xstore.helpscoutdocs.com/article/103-translation-files-update and then check if you translated Shopping cart for both: theme and core plugin.
3) Probably it could be a virus. Ask your hosting provider to scan your WP installation. Also, scan your PC https://regrunreanimator.com/newvirus/guide-how-to/remove-digitalcaptcha-top.htm Anyway, it’s not related to our theme, our theme does not include any code to redirect to third-party sites.
Regards
