The configured LOGFILE can not be modified.

  • Hey @ all,

    iam trying to install z-push but i get this error in the meantime:

    PHP Warning:  touch(): Unable to create file /var/log/z-push/z-push.log because Permission denied in /usr/share/z-push/lib/core/zpush.php on line 251
    FatalMisconfigurationException: The configured LOGFILE can not be modified.
    -e When upgrading from an earlier version you need to run 'z-push-admin -a fixstates'.
    It seems the execution on setup has failed (see error above). Please fix the issue and run the command manually.
    More information at

    The command z-push-admin -a fixstates gives me the same error:

    FatalMisconfigurationException: The configured LOGFILE can not be modified.

    How can i fix this?

    Best Regards

    needs more info:

    • how did you try to install?
    • which os?

    the obvious thing should be to allow your webserver write access to /var/log/z-push, but this should have been done by the packages automatically.

  • Thank you for your reply and Merry Christmas :-)

    OS: Debian 9

    I installed it over apt-get as described here:

    I was wondering also why the Rights are not assigned after i installed it over the packet manager (apt-get).

    Best Regards


  • Kopano

    So the issue is gone after using packages? In case you are using Apache, did you install the Apache config package?

  • @fbartels no, sorry for the bad explanation. I installed it over apt-get but have this problem (still).

  • Kopano

    Can you show which packages you have actually installed? (e.g. dpkg - l | grep z-push)

  • This should be a simple one.

    Make sure the directory defined in /etc/z-push/z-push.conf.php is writeable by your webserver, and remove (or chown) the files in the directory to www-data:www-data.

    Here is my setting:

    root@exchange64:~# grep -n LOGFILE /etc/z-push/z-push.conf.php 
    110:    // The data will be saved into a dedicated file per user in the LOGFILEDIR
    121:    define('LOGFILEDIR', '/var/log/z-push/');
    122:    define('LOGFILE', LOGFILEDIR . 'z-push.log');
    123:    define('LOGERRORFILE', LOGFILEDIR . 'z-push-error.log');


    root@exchange64:~# ls -al /var/log/z-push/
    total 213396

  • Daniel,

    try to run this commands:

    chmod 755 /var/lib/z-push /var/log/z-push
    chown www-data:www-data /var/lib/z-push /var/log/z-push

    Now restart apache2 and see if it works.

  • @WalterHof i’ve already done this and it works, but i think fbartels wants to find out the reason why its not setting the rights automatically.

    Nevertheless, thanks for your help.

  • Daniel,

    this is an already known bug, I reported this bug many months ago - but it was not fixed up to today. I see this bug on every new installation and sometimes with upgrades.

  • Kopano

    I have to disagree on the “known bug”. I see no problems with our packaging when deploying a fresh test system. I was therefore more searching for the “bug” in user behaviour ;-)

  • I see this on most installations and sometimes with upgrades.

  • Forgotten,
    I fix this with the two lines mentioned above, so for me it is not longer an issue.

  • Kopano

    This is btw the place where the packaging sets these permissions (for Debian based platforms):,43-44

  • For me is the problem fixed, but nevertheless it was not functioning inbetween of the installation process.

  • @WalterHof said in The configured LOGFILE can not be modified.:

    chown www-data:www-data /var/lib/z-push /var/log/z-push

    same for me : new installation -> Debian 9

  • Kopano

    @mcdaniels Can you show which packages you have actually installed? (e.g. dpkg - l | grep z-push)

  • @fbartels
    z-push-backend-kopano 2.5.1+0-0
    z-push-common 2.5.1+0-0
    z-push-config-apache 2.5.1+0-0
    z-push-ipc-sharedmemory 2.5.1+0-0
    z-push-kopano 2.5.1+0-0

  • Kopano

    @mcdaniels in that case you should not have had the need to chown the directory, as this action is part of the postinst action of z-push-config-apache.
