After seeing this error I went to my Notification Preferences to see what my current Time Period was setup as and thats when I noticed the following.."User does not have a valid timeperiod for deployment. The timeperiod will have to be configured from the Core Config Manager."

Does anyone know a solution to this? I've tried Firefox, Chrome, and Safari. I've tried clearing my cache, restarting the server, etc... The Time Period form is just gone.
