    The Additional configuration directives field is not available with the Power User View, you need use the Service Provider view

    I did as described, upped max_input_vars to 3000, while only 2000 is needed. Prestashop still gives me notifications about needing to up that value to 2000. Does PHP need to be restarted after such a change?
