it seems like the double-opt-in option doesn’t work with Safari. It correctly gives me an error in Chrome and FF, when trying to proceed without checking the box. However in Safari I am able to register even without checking. Any thoughts?
I somehow never replied to you, sorry about that. I meant the check box that tells you about your statutory rights (required in the EU). It doesn’t work in Safari and also Internet Explorer (the user doesn’t have to tick the box in order to complete the registration).
