My ISPconfig doesn't apply changes

Hi to all. I have the following problem:

I have an ispconfig/debian sarge system which worked fine for 6 months. But now when I make any config change using the control panel (useradd, usermod, site add, etc), the ispconfig works perfectly on screen, but it doesn't apply the changes on the system.

For example:
I add a new user and it doesn't appear on /etc/passwd
I add a new site and the directory /home/www/sitename its not created
I add a new DNZ zone, but /etc/bind/pri.sitename its not created...

In the control panel, everything seems perfect.

Any help would be very appreciated.

 

Hi Till, I've checked your post, and its was helpfull, but I tried to generate a segfault, but instead I had this:

vs101:/# /root/ispconfig/php/php -q /root/ispconfig/scripts/writeconf.php
start
INSERT: 25
INSERT: 30
INSERT: 32
DELETE: 33
chmod: cannot access `web32_a:web32': No such file or directory

INSERT USER: 77

INSERT USER: 72
chmod: cannot access `web25_gusta:web25': No such file or directory
ERROR: Nothing parsed, nothing printed <BR>
INSERT USER: 75
DELETE USER: 76
ende


The users where the errors occurs where added by me using shell commands (useradd, usermod,etc...).

One more question... is that command the one that apply the pending changes made by the ispconfig control panel ? If the answer is yes, what if I manually run it after changing something with the ispconfig, would it work as an temporary solution ?.

Thank you in advance.
