I've tried restarting, used omv-firstaid and yet everytime I try to login it says "Incorrect username or password".
The strange about this is that I didn't restarted the machine, and I believe it didn't restart itself, I was by it's side all the time and it didn't beep. I used it like 2 hours ago and it worked flawlessly, now it's just not letting me log in. Used different browsers, but it didn't work anyways.
What else can I do?
