I recently switched antivirus programs and now when I access this site I first get this error:
Your connection to this website is not safe due to expired certificate and was blocked.
I can click through, but it's still annoying.
Also, certain lines aren't wrapping properly (like the message body form and the line with all the markup buttons), and since it occurs on both Firefox and Chrome, I suspect it has to do with this certificate issue and how it's interacting with my AV.
