I was very happy with HTTPS, I have got a different subdomain to use with SSL and I'm forcing SSL Administration and using SSL Logins.
It was working superb until last JetPack update as Publicize feature stopped working. Posts stopped to be publicized if I use dashboard on secure domain.
So I had to disable forcing ssl administration. Even opening Jetpack management screen gives error about secure content, I think they have external components.
I hope there is a solution for this.
