My flash just stopped working. It is being reported by Windows users as well as Linux users.
Here are some work arounds that worked for me.
One user says:
"I solved the problem by deleting the "PepperFlash" folder in ~/.config/google-chrome/
This is not a permanent solution. The PepperFlash folder recreates itself with its content after a while. Just delete again until Google officially fixes this."
Another says:
"Unfortunately Jan's solution didn't stay for long for me.
But what I did later was go to chrome://plugins/ in the address bar and disabled
/home/evan/.config/google-chrome/PepperFlash/11.5.31.138/libpepflashplayer.so"
