How to enable exec()?

I am trying to install the fiverscript.
everything is ok except to the part where users wants to upload a file.

I am getting an http error from the script.

at the script support they said that I need to have the Ability to run PHP from the command line (CLI) with exec() and the Ability to execute background processes with exec(“binary > /dev/null &”)

so… anyone know how to do it???

thanks !

Should work without any changes. We don’t have anything set up that’d restrict exec().

What do you mean?
Do you have fiverscript installed on dreamhost server?
