I need to change for prestashop the value: max_input_vars
debian fresh Jessie 8 install
php fpm (i think so, and myabe hope:)
imscp 1.3.14
I edited usr/local/etc/imscp_panel/php.ini just removing ; and change to 10000 then
service imscp_panel reload + /etc/init.d/apache2 reload + /etc/init.d/php5-fpm reload
no way to see it working...
