Is it possible to disable functions using FastCGI to specific sites or to all sites, but not mess with the ispconfig server. I can add it to the /etc/php.ini, but then it adds it to ispconfig as well. In Ispconfig 2 there was a seperate php.ini file, but I don't see one in ISP3. I also tried adding it to htaccess and also the "Options" tab in ISP3 admin for the website using: php_admin_value disable_functions "exec,shell_exec,system" but did not work even after restarting apache. I would like to use FastCGI with Suexec because I want to be able to upload files to a directory without making the directories 777. I would like to disable functions like exec,shell_exec,popen,dl, Etc. I am not sure wich ones are used by ISP3 and I don't want to chance it.
