my computer is doing the same thing..chrome works but safari is not loading certain websites properly. It's main when I go to for instance....tmobile.com. That will load but once I hit log in it brings me an error message. Its been doing this for every website when I try to log in to my accounts.

I'm unable to login in to a particular website that I just recently logged into. I've contacted the online support team

of the merchant and they tried everything on their end. Please advise!
