user_prefs not working

[John Tice]

Running SA on a Cpanel VPS that had an outage yesterday, when it came  
back up SA is not using any of the user_prefs files in the individual  
accounts. Support doesn't know what to do. The user_prefs are still  
in the proper places but just not being read, or not influencing the  
scores, no whitelists, etc. Can anyone offer troubleshooting advice  
that I can use directly or pass along to the support folks? Thanks.
