Hello, @loiscapirosi,
1- The error appears because of the user roles. You have admin access and you have to change it to tester/developer here is an article to understand it better and learn how to solve it: https://stackoverflow.com/questions/58778302/instagram-display-api-insufficient-developer-role
2- The image you changed appears just fine on the frontend in that section there are no sample images see the screenshot for a better reference: https://postimg.cc/f3Hy2tMS
3- a) You can change and translate it from the theme language files: https://paonkids.com/wp-admin/admin.php?path=languages%2Floco%2Fthemes%2Fxstore-es_CO.po&bundle=xstore&domain=xstore&page=loco-theme&action=file-edit https://postimg.cc/NyhkGjVn https://postimg.cc/K497kNwB
