This is the same string you see at the very top of the [phpinfo()](https://www.php.net/manual/pt_BR/function.phpinfo.php) output. For the name of just the operating system, consider using the **`[PHP_OS](https://www.php.net/manual/pt_BR/reserved.constants.php#constant.php-os)`** constant, but keep in mind this constant will contain the operating system PHP was _built_ on. * On some older UNIX platforms, it may not be able to determine the current OS information, in which case it will revert to displaying the OS PHP was built on. This will only happen if your uname() library call either doesn’t exist or doesn’t work. * In this case, can you confirm with your host that this function is enabled on your site? If it isn’t active, there are chances that it will break the website. * Looking forward to helping you get to the bottom of this! * Plugin Support [Matheus Martins](https://wordpress.org/support/users/matheusfd/) * (@matheusfd) * [2 years, 2 months ago](https://wordpress.org/support/topic/php-fatal-error-419/#post-17491802) * Hi there. * It’s been a while since we’ve heard back, and I know troubleshooting needs a little extra time. I’m marking this as resolved for now, but if you still have questions, you can send them along right here, and I’ll be happy to hop back in. * Have a great day!
