Fix this week
The plain, unlocked version of your site still works
This is the exact wording EverThread uses when it finds this on a customer's site, written for someone who runs a business, not a server. The example site here is yourbakery.com.
What we saw
Typing yourbakery.com without https loads an insecure page instead of switching to the secure one.
Why it matters
Visitors who arrive that way have no padlock, and anything they type can be read on the way.
How to fix it
Ask your developer or host to redirect all plain http traffic to https. It is a standard one-line setting.
For your developer
http://yourbakery.com returned 200 with no redirect. Add a 301 to https:// for all paths.
