Hi emmyone,
Just a generic thought as we don't have any details other than "your website". For starters, who's hosting your site? Is this a separate site that you have? Are you then linking to Square's online site for sales or is your website just through Square? For example, we have a site that is separate from Square's free online site. Our site host handles the "https" listing and provides the security certificate - this is all included with our yearly fees. We then have a link to Square's free online site for online shopping, they (Square/Weebly) handle the "https" and associated security settings.
