Can't access editor. Tried clearing history, cookies, and clearing/flushing DNS cache

Hey everyone, I’ve spent several hours this morning trying to log in on Safari and Chrome. Tried clearing history, cookies, and clearing/flushing DNS cache but nothing is working.

Chrome tells me my browser is unsupported.

Safari was giving me a chance to log in but then logged me out afterwards saying I wasn’t allowing third party cookies although I allow cookies on Safari.

Is there anything I’m missing?
