Hello Jacopo,
I checked on your store and I see that you enabled the web review creation restriction feature here:
https://judge.me/settings?jump_to=web+reviews
By enabling that, the button to write a review gets hidden.
That being said, if you disable it to make the button visible again it will be white now, not blue anymore.
Let me know if you need further assistance or send us an email to our support email address: support@judge.me
Kind regards.
Jacopo Furioso
