getenv() has been disabled for security reasons

Is this your own server, or shared hosting? If it's shared hosting, you should ask them as they would have to enable getenv(). There may also be a way to enable it via the control panel (like cpanel or something). If it's your server, you'd just have to enable getenv() in your php.ini. In php.ini, you'd look for a line with disable_functions and remove it from there so it's enabled.

The same would be true for the phpinfo() function (I assume that's what you mean by "info.php not working").

@jlrdw I think there's enough info to answer lol. It says exactly what's wrong.

saving php.ini with

disable_functions=

worked for me
