It appears to be fixed now, except I find that I need to move the cursor right or left in the password field to get the button to activate.
That was always an issue here so not sure it can be fixed.
Not fixed here. Still the same garbage in the login box. I won't accept the problem has been resolved until
1) several people confirm that normal interface has been restored and
2) We get through more than 48 hours without the text reverting to gibberish.
Yes the problem is known, yes the problem is being worked on, no we don't know when any patch for the problem will be rolled out. We'll know when everyone else knows.
But it's not fixed yet.
Logged out, logged back in and at last the login box (at least) is showing the correct text labels.
Still seeing the weirdnesses in other places but perhaps after a reboot they'll be back to normal too.
