errors rotating logs

[Root <root@xxxxxxxxxxxxxxx>]

errors occured while rotating /var/log/httpd/access

error running prerotate script --
                                leaving old log in place
-----------------------------------------------


My questions are:

1.- Why the GUI dont create the files web.log, ftp.log, mail.log in NEW
virtual sites....?
2.- Why logrotate dont updated them and send me every day a message as
the one I posted above....?
3.- What can I do pleaaasseee.....?

Some interesting information about my RAQ3:

-  Cobalt installed software:

---------------------------------------
- my /etc/cron.daily/logrotate file contains:
#!/bin/sh
/usr/sbin/logrotate /etc/logrotate.conf

--------------------------------------

- my /etc/logrotate.conf file contains:
# see "man logrotate" for details
# rotate log files weekly
weekly
# keep 4 weeks worth of backlogs
rotate 1
# send errors to root
errors root
# create new (empty) log files after rotating old ones
create
# uncomment this if you want your log files compressed
compress
# Put in a generic size limit so things don't go wild
size 1M
# RPM packages drop log rotation information into this directory
include /etc/logrotate.d
# no packages own lastlog or wtmp -- we'll rotate them here
/var/log/wtmp {
    monthly
    size 2M
    create 0664 root root
    rotate 1
}
/var/log/lastlog {
    monthly
    size 2M
    rotate 1
}
# system-specific logs may be configured here
--------------------------------------------------

I didn`t make changes in any of the configuration GUI files.

Sorry for my poor writing and grammar english.  I am from Spain ;-(

Thanks in advance to anyone who can help me. I am lost!
