[SPAM] qmailadmin and maillist editing not working

i installed a fresh install on my server
which is centos 6 x64.

other package's versions are like that.

vpopmail-5.4.33
ezmlm-idx-7.1.1
qmailadmin-1.2.16

all is fine but.
when i try to edit a maillist config like:

- remote management
- subscription methods
- message archiving
etc...

and then click on "save" then i am back to main maillist screen.
when i check the settings, i see that nothing has been changed.

what can i do to solve this?

thanks...
