Hello, @Stelio,
If you would like to modify the text on the page and buttons on your account page when not logged in, you will need to make the changes in the Theme and WooCommerce plugin language files.
For translating the site, you can use the Loco Translate plugin. For more information, please refer to our theme documentation here: https://xstore.helpscoutdocs.com/article/30-base-theme-translation.
To begin, please go to Loco >> Themes >> XStore and edit the particular translation language, then click the SYNC button. After that, search and translate the words as needed.
Next, go to Loco >> Plugins >> XStore-Core and edit the particular translation language, then click the SYNC button. After that, search and translate the words as needed.
Finally, go to Loco >> Plugins >> WooCommerce and edit the particular translation language, then click the SYNC button. After that, search and translate the words as needed.
We hope this information is helpful.
Best regards,
8Theme’s Team
