people visit my site and all they get is a blocked page with the message that reads "Your connection is not secure"
The owner of propertyavenuemag.com has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website.
I keep getting this error.
I am unsure how to make this work. I don't think that it has to be secure site as it is outfitted with Buy Now buttons from Shopify.
It appears that your site is redirecting to HTTPS without having a SSL certificate. You may want to confirm you have a SSL certificate issued for that particular site. If you do, our Customer Care may be able to review and see if there's any issues.
Hope that helps.
