Au cas où, on peut, si je ne me trompe pas, normallement laisser safe_mode activé, mais il faut rajouter le bon path dans safe_mode_exec_dir dans le fichier /usr/syno/etc/php.ini
; When safe_mode is on, only executables located in the safe_mode_exec_dir
; will be allowed to be executed via the exec family of functions.
safe_mode_exec_dir = /chemin/vers/script/
EDIT : euh, bon, ok, je me trompe certainement, après quelques recherches sur le web (http://www.php.net/m...e.functions.php), j'ai trouvé cela :
Functions restricted/disabled by safe mode
This is a still probably incomplete and possibly incorrect listing of the functions limited by safe mode.
shell_exec() (functional equivalent of backticks) This function is disabled when PHP is running in safe mode
