Hi
Shell scripts and shell commands are disabled for security reasons
any kind of shell access is blocked
Nor do you have permission to configure the server
But you can creating .htaccess file inside the htdocs folder that will run the URL RW
Check well it code and that is located inside htdocs
If your scripts tries to write outside htdocs:
Scripts can only write to the htdocs directories they are in. Any directories outside the htdocs dir cannot be written - due to the open_basedir restriction
