Once you decide to go SSL, you realize browsers have come a long way.
The little security icon in Chrome indicated I had some issues with my site.
That not everything was using https… Hmmm…
I came accross the flask-SSLify module: https://github.com/kennethreitz/flask-sslify
That didn’t solve the warning indicator. The thing NEEDS to be green!
Digging deeper… I loaded jquery-latest over http.
Changed to https://code.jquery.com/jquery-latest.js .. fixed that.
Gravatars are still grabbed over Http. Jimeny.
Changed to https://www.gravatar.com/avatar/ .. fixed that.
