  • I've seen this a few time in the last two months or so. No ability to reproduce it on demand, and it's been a while so perhaps it is finally gone. Nov 28, 2011 at 19:15
  • I've never seen this message on Electrical Engineering, where it's also enabled. Nov 28, 2011 at 20:53
  • I agree it does not seem reproducible, I have visited both networks again a few times but haven't seen the error again. Nov 30, 2011 at 8:27
  • @balpha: I saw this problem recently on Electronics SE when viewing it on HTC Desire S Android device.
