I noticed that I cannot use shell_exec in Plesk because safe_mode is on. When I turn it off, it works. My script looks like this:PHP: <? echo shell_exec('uptime'); ?> When I add PHP: ini_set("safe_mode",0); It just won't work I also tried it using /home/httpd/vhosts/mydomain.com/conf/vhost.conf: This also won't work, I restarted Apache but no changes. I don't want to change this setting for the complete webserver, only for this domain. Does anyone know how I can do this?
