Hello,
1) Follow this article to translate the theme – https://xstore.helpscoutdocs.com/category/18-theme-translation , and WooCommerce – https://docs.woocommerce.com/document/woocommerce-localization/ Do not forget about Core plugin. Loco translate > Plugins > XStore Core > New language > Choose a language + Choose a location – System > Start translating. 2) If you want to run the fresh WordPress installation you can use WordPress Database Reset plugin https://wordpress.org/plugins/wordpress-database-reset/ The plugin can be used to remove all the existing content and install a new version from scratch. It is recommended to disable the theme https://prnt.sc/unle03 before the reset. 3) What features disappeared? Maybe we will be able to help restore them without the reset.
Regards
