GroupChat no Work - Need some expert advice

I upgraded to the latest version on openfire yesterday. Soon after I tried a group chat and it no longer works. This featuer may have been broken before the upgrade because it’s very rarely used.

The isse from the client is that you recieve a message that the server isn’t repsonding when you try to create a conference.

On the server I get the error like the one below when I try to create a room. I’m also getting errors that some rooms already esist even though I cant see them in the list. Basically group chat appears to be totally hosed. Please let me know the best way to re-install / rebuild group chat.

Exception:
java.lang.IllegalArgumentException: Illegal JID: test@group chat.tulspk

Groups that have not been used in a long time become invisible but are still there. you need only join them once to make them visible again for a time. I would check your settings to make sure you are not restricting group creation in any way.

I get the same error when I try to join and group or create a conference on the fly from the spark client.
