Loco translate > Themes > XStore > add the language you need Translate the necessary strings.
Do the same for the XStore core plugin (Loco translate > Plugins > XStore core).
Also, don’t forget to choose the site language in Settings > General.
Note:
– You need to translate the parent theme. The child theme should be translated only in case you added custom code in child theme that includes localization functions.
– Make sure you placed translation files of the theme into the /wp-content/languages/themes/ folder with correct names (language name and xstore theme suffix, e.g xstore-de_DE.po, xstore-de_DE.mo). Click Sync button https://xstore.helpscoutdocs.com/article/103-translation-files-update, continue translation.
