Was having the same trouble and turning off the HDMI control worked for me!
Control for HDMI turned off yes it works,, leave it up to PlayStation
Go to your PS3 settings and disable the HDMI, so its off. then it will work, dont know why but it does.

Can you please check the web site to see if your stats are visible there? Are you using the console application or mobile app? Try unlinking your gamer profile then link it again.
