I'm Alex, with the Shopify team!
I've had a look at your site and I'm seeing the green icon padlock there - this indicates that your SSL is available:
Can you check the domains section of your admin to confirm if you're still seeing this warning? If not, it's likely that your settings were updating and are all set now, you should be fine going forward. If you're still seeing an issue there, however, please do reach out to us and we'll be happy to take a closer look into this for you!
Hope that's helped! Please feel free to let me know, and you can always give us a call or start a live chat at any time. We're open 24/7 for your convenience and always happy to assist!
