I had a bit of a scare the other day after a simple reboot of my Zenoss 4.2.4 monitoring server. When the Zenoss server came back up, I went to login like usual and I received the dreaded "A Zenoss error has occurred" message! Below it was the following:
Type: <type 'exceptions.KeyError'>Doesn't look pretty does it? Everything seemed to be working still, I was still getting alert emails, but I could not login to the user interface to save my life!
Traceback (most recent call last):

Well, I found a solution in an archived community support thread. To fix it I did the following to fix it by SSH'ing into the Zenoss server:
- su zenoss
- from Products.ZenUtils.Security import activateCookieBasedAuthentication
- zopectl restart
After that, I was able to login fine! Each of the above are one line commands in the terminal.
I hope it helps you out!
