I`m using : Debian Jessie Ispconfig 3 Hello i tried to enable allow_url_include but without succes. /etc/php5/apache2/php.ini
Edit the file /etc/php5/cgi/php.ini and restart apache afterward. The ini file you edited is for mod_php only and mod_php should not be used and the default for websites is fastcgi mode which uses the /etc/php5/cgi/php.ini file.
