Ubuntu 9.10 x86_64 server, webmin 1.493 (installed from debian repository )
I got error after tryed to install jabber or jabberd2 package:
The Jabber base directory /var/lib/jabber does not exist. Either Jabber is not installed, or your module configuration is incorrect.
Yes, I tryed to "Refresh Modules" and to "Reboot system" :)
P.S. The same problem described on post https://sourceforge.net/projects/webadmin/forums/forum/600155/topic/3447721
