Cannot identify a valid IP address

Hi,

there are servers – like mine – that do not add their IP to the environment. Therefore you get error in the metabox2 “Cannot identify a valid IP address” (and “PHP Notice: Undefined index: SERVER_ADDR” in debug.log).

class-admin-settings.php > line 298

You might want to get the IP using gethostbyname. Works like a charm ??

if ( isset( $_SERVER['SERVER_ADDR'] ) ) {
  $ip = $_SERVER['SERVER_ADDR'];
} else {
  $ip = gethostbyname( $_SERVER['SERVER_NAME'] );
}

Cheers
Marc
