Hi there @piccemozioni ??
Thanks for reaching out about this. Let’s troubleshoot it together!
on the product fields, if I click on “Facebook” I see completely white. I can’t sync the product. how can i fix?
Could you please provide us with a screenshot so that we can see what you are describing?

There is also a walkthrough guide here: https://en.support.wordpress.com/make-a-screenshot/
Additionally, to get an idea of how your site is configured, could you please share a copy of your site’s System Status, as exemplified here? Once you’ve done that, you can paste it here or into our https://quickforget.com/ service and send that secret link here.
Looking forward to hearing from you!
