Então eu sou relativamente novo no Cron Jobs e me deparo com um muro tentando fazer com que esse cron job específico funcione. Tudo que eu quero é que uma página da Web do PHP seja acessada diariamente. Ao acessar a página PHP, o cron job ativará o script dentro do qual envia um email para usuários específicos. Aqui está o código do trabalho cron:

php -q /home/sitename/public_html/scripts/emailnotifications.php

Infelizmente, todos os dias às 1:00, recebo esta mensagem de erro e ninguém recebe o email.

Eu não tenho acesso shell ao servidor ou acesso a nenhum arquivo de configurações do servidor (exceto php.ini). O que devo fazer para que esse script seja executado diariamente?
