in lighttpd.conf (on Debian /etc/lighttpd/lighttpd.conf) add "broken-scriptfilename":

fastcgi.server = ( ".php" => ((

                    "bin-path" => "/usr/bin/php5-cgi",

                    "socket" => "/tmp/php.socket",

                    "max-proc" => 10,

                    "broken-scriptfilename" => "enable"

             )))

else you will get the error saying "There has been no

contact with the remote server for several minutes.."

after logging in on DIMP.

in php.ini (on Debian /etc/php5/cgi/php.ini) enable PATH_INFO by setting fix_pathinfo to 1:

cgi.fix_pathinfo=1
