Admin Page Control

Hello,

ejabberd-1.1.1.tar.gz - Source Compiled

When I tried to add an account in the admin page, it said like this: "A page not found".
I do not know why but I cannot add a user but can remove it.

And another is that I cannot manage ejabberdct1 as well.
When I type "./ejabberdct1", a message appears like this below:

[root@mail ebin]# ./ejabberdctl help
usage: ./ejabberdctl command [arguments]

console - open an Erlang console
help - display this help and exit
showconfig - show ejabberdctl configuration
start - start ejabberd

I think the content to be appear should be the same as below:

% ejabberdctl
Usage: ejabberdctl node command

Available commands:
status get ejabberd status
stop stop ejabberd
restart restart ejabberd
reopen-log reopen log file
register user server password register a user
unregister user server unregister a user
backup file store a database backup to file
restore file restore a database backup from file
install-fallback file install a database fallback from file
dump file dump a database to a text file
load file restore a database from a text file
import-file file import user data from jabberd 1.4 spool file
import-dir dir import user data from jabberd 1.4 spool directory
registered-users list all registered users
delete-expired-messages delete expired offline messages from database

Example:
ejabberdctl ejabberd@host restart

How to install ejabberdctl to fix those problems?

Thank you
