Can't change php.ini

[Kubek]

Hello,

I followed this tutorial: http://www.howtoforge.com/perfect-se...nx-ispconfig-3
I am using php short open tags on my site.
I opened phpinfo() page and firuged out that php.ini is in /etc/php5/fpm
So I changed short_open_tag to On, restarted nginx and php5-fpm:

service nginx restart
service php5-fpm restart

But my phpinfo is still showing "short_open_tag = Off"
So i tried few more times to reboot, restart nginx and php5-fpm I also tried to change it in "Custom php.ini Settings" in ISPconfig, and tried Resync Tool but still "short_open_tag = Off" on phpinfo() page

Please help me
