Pro-Tip for Admins: Always use absolute paths in your cronjobs (e.g.,
/usr/bin/phpinstead of justphpand/var/www/script.shinstead of./script.sh). Cron environments running viacrontab -ehave a highly restricted set of environment variables and often won’t find globally installed binaries without their full path.
