Conference unable to join room

Hello

I got a problem with muc mod on spark. Each time i try to enter a conf room, i got the message “unable to join room”. On psi it works.

On the log files i have this :

14 nov. 2007 09:57:24 org.jivesoftware.spark.util.log.Log error

GRAVE: Error in disco discovery.

same here with openfire 3.7. any luck? conference rooms will not come up in spark

I had to destroy the default conference service, create a new service and readd all the rooms.
