2 – i need to change the button link “back to store” (voltar para a loja). the link redirects to wrong page (i don`t use the default store products page), and i need to redirect to home. is possible?
Thank you for your questions. We have moved them to another topic.
1. You can easily change it via POT file of the WooCommerce. We suggest you use Loco Translate plugin for that. Here is a video tutorial that should help you https://www.youtube.com/watch?v=tAFq1yTfWfU
Be sure all your translations files are stored in wp-content/languages/themes folder and not in the theme folder itself to prevent losing changes after update.
