Member list does not work

I’ve migrated from Openfire 3.3.3 to 3.4.5. After that I am not able to get members list from the specific room.

I am using this command

<iq from=‘hag66@shakespeare.lit/pda’

id='disco4'
    to='darkcave@macbeth.shakespeare.lit'
    type='get'&gt;
  &lt;query xmlns='http://jabber.org/protocol/disco#items'/&gt;
&lt;/iq&gt;

Am I doing something wrong?
