Please try to use the vlogger version from Ubuntu to see if you get the same problems there:
apt-get install vlogger
then edit the file:
/etc/apache2/sites-available/ispconfig.conf
and replace the line:
Code:
CustomLog "| /usr/local/ispconfig/server/scripts/vlogger -s access.log -t \"%Y%m%d-access.log\" -d \"/etc/vlogger-dbi.conf\" /var/log/ispconfig/httpd" combined_ispconfig
with:
Code:
CustomLog "| /usr/sbin/vlogger -s access.log -t \"%Y%m%d-access.log\" -d \"/etc/vlogger-dbi.conf\" /var/log/ispconfig/httpd" combined_ispconfig
