hi and thanks for your answer
It's complicated for me to explain. because i don't really speak english.
I'm on debian 6 too and isp 3.
normally when you have deb + ispconfig and when you check your phpinfo.php you have 1 line :
Loaded Configuration File : /etc/php5/cgi/php.ini
Now by me it's :
Loaded Configuration File : /etc/php5/apache2/php.ini
And i want to change that and have /etc/php5/cgi/php.ini
The raison is : when you modify your php.ini in the apache2 directory you have mistake with ispconfig. that .ini must be original.
Now if i want to access at ispconfig whitout problem i send the original php.ini with sftp and i restart my apache. I make my modification in ispconfig and when i have finished with ispconfig i resend my php.ini (modified).
Now i want only change that line on my php.ini.
I hope you have understand what i explain.
Thanks for all.
