baronalloway on "[Plugin: MailChimp for WordPress] Mixed Content Warning: HTTPS"

I'm in the process of migrating my site to https.
I am getting a "mixed content warning" related to your plugin, because it "contains a form which targets an insecure endpoint 'http://<MAILCHIMP URL HERE>'

Is it possible to modify this plugin so it targets my mailchimp URL with https?

Thanks!
