bug with reverse dns lookup call

Hi,

I’m not sure how you handle contributions but we encounted a bug with this plugin where the wp_remote_post call on line 1375 would return a wordpress error object instead of an array where a non-successful HTTP request was made.

We have added a check to test if $result is an array and is not a wp_error – if either of these fail we set $ips[$host] = false; as in the case where an empty body is returned.

The full code is:

//catching unhandled exception where a wordpress error object will be returned in cases where the http call fails
if (!is_wp_error($result) && is_array($result)) {
    if ( empty ( $result['body'] )) {
	$ips[$host] = false;
    } else {
	$body = json_decode( $result['body'] );
        $ips[$host] = isset( $body->ip )
		? $body->ip
		: false;
    }
} else {
    $ips[$host] = false;
}
