I used Poedit to translate the theme, but some items remain in english :
“whishlist is empty”
button “return to shop”
I found them in basel\inc\woocommerce\wishlist\class-ui.php
I change the file and uploaded it in my child theme using the same path, but they remain in EN in my front-end.
Please check the video tutorial to see how to save the translation file correctly. You can remove the plugin and translations would remain. Also, translations would remain after each theme update.
