I've gotten that message, but only in a specific context.
I'd opened and was playing about 10 Bloody Pingu windows simultaneously, (to maximize the odds of a high score quickly - start one then just start the next), and lo! - one did get a new board high score.
I excitedly posted it, and got that message - "No permissions".
Never got that message other than when using multiple windows.
“When beggars die, there are no comets seen;
The heavens themselves blaze forth the death of princes.”
