There are hundreds of reports of struggling with this error message. It returns in many very different situations.

"please contact the site administrator" all by itself is useless to the site administrator - or developer. Please, please, please attach a little more info to this error message. Since it sometimes occurs when there doesn't appear to be anything wrong, right now it is worse than useless.

Are you using Suhosin to protect your PHP environment?

I was, and I got this error message whenever I tried to submit a complex page (permissions/large menu etc.etc.)

I changed the suhosin.post.max_vars to 1000 (it's in the suhosin.ini file in the conf.d folder for php (normally /etc/php5/conf.d )

This appears to NOT be a Drupal bug, just the security on your server being over enthusiastic.

I found this out by going to the Apache log file and running a tail -f of the site errorlog. This show me it was a POST error, and by googling that error in found this link. https://bugs.launchpad.net/ubuntu/+source/php-suhosin/+bug/158645

I hope this helps.
