Error reading settings in wiki and profile manager

Question

I have just upgraded from Snow Leopard Server to Lion server.
I now have the following errors in server app:-
Wiki : message "Error Reading Settings"
Profile Manager: message  "Error Reading Settings"
What do I do to get my wiki back!
When I visit my default ssl Wiki I get the following:-
Collaboration::PGCConnectionError in Sources#index
Showing /usr/share/collabd/coreclient/app/views/layouts/application.html.erb where line #5 raised:

Answer 1

I did a clean install of Lion/Lion Server, but I ran ino the same problem too with "Error Reading Settings" for both the profile manager and the wiki.
INVESTIGATION: I checked to see if the postgres database (which I presumed was were the settings were being read from).
# sudo serveradmin fullstatus postgres
postgres:dataDirHasBeenInitialized = yes
postgres:PG_VERSION = "9.0.4"
postgres:dataDir = "/var/pgsql"
postgres:postgresIsResponding = no     # !!! why isn't it responding???
postgres:dataDirIsDirectory = yes
postgres:PGserverVersion = 0
postgres:dataDirExists = yes
postgres:setStateVersion = 1
postgres:state = "RUNNING"
PROBLEM: The postgres service hadn't been started properly; I found this by doing the following:
# sudo serveradmin stop postgres
postgres:state = "STOPPED"
# sudo serveradmin start postgres
postgres:error = "CANNOT_START_SERVICE_TIMEOUT_ERR"
FIX: The postgres service couldn't create the log file because it didn't have permission. I did this to fix it, then simply restarted it and all was well:
# sudo chmod 777 /Library/Logs/
# sudo serveradmin start postgres
postgres:state = "RUNNING"
I hope this helps someone.
