Can anyone explain to me what may have happened for analytics to just stop reporting site traffic? The script is still in place and I used the most recent.
Did you just switch to the new one? If you somehow have both codes on the same page it will break it.
maybe try to reinstall the code.. and if the problem still occur try to visit their help center.. http://www.google.com/support/googleanalytics/
It may take some time for stats to show up. Also if you have different timezone set for your site, the stats may be delayed.
Mine is working fine, if the new code doesn't work for you, you can try using the old legacy code - still tracks all the current features of Google Analytics...
Mine´s working fine too, maybe it´s updating or there´s an error and´s taking too long to update. Wait a couple more days after that re-insert the code (html/java) in the site again. If it dosen´t work then contact google analytics team.
