Unfortunately I can not recreate this. Can you tell us if you get the same issue if you refresh the same page and try then?
It could have been that some resource did not get loaded, causing this issue for you, but as I can not recreate it on my side I can not be sure what it might be.
Seeing that you were logged in when you posted this and your post suggests that it is only that page that was affected, I believe that all others are working properly for you?
Is it because of Safari? Yes, I can log in via my forms page.
Mac with Safari and Chrome is what our developers use each day, so I do not think that this would be causing the issue. Feel free however to check if you experience issue only with it. I have no issues on Chrome nor FireFox, but I am using PC, not Mac.
Can you tell us if you are still experiencing the same issue?
If so, what happens if you press enter while your cursor is within the password or username field (if the button is not working)?
