I have Google Analytics on my webpage. The reports show properly as far as I know. But when going through settings I saw this:
Notice the date => I have checked and tracking is on the home page. Why am I getting this error?
Have you switched to the new GA interface? This appears to be a known bug, according to a response here and in a bunch of other threads I've run across, going back at least as far as April. You might try trawling around in the Analytics forum for a definitive/original statement of that; I haven't managed to track it down.
If you're still getting stats correctly, I wouldn't worry about it too much. That date, immediately before the Unix Epoch, mysteriously popping up often indicates a glitch.
