Hello, Pedro Monteiro,
1/ Thank you for reaching out to us. We apologize, but we are having difficulty understanding your request. Could you please provide more information so that we can better assist you?
We look forward to hearing from you.
2/ Do you want to change the text “New”?
This text comes from XStore, so you can use translation files to change it. Install and activate the Loco Translate plugin > create a translation for XStore theme > change English text and disable the Loco plugin https://xstore.helpscoutdocs.com/article/30-base-theme-translation
When you will need to change the text back, activate Loco plugin and do this, or just delete translation files.
Kind Regards,
8theme team
