Hello,

I had the same problem.. I did a quick fix by myself and It’s working now.

This is the function that I changed:

function mc4wp_get_request_ip_address() {
    $ip = null;
    if ( isset( $_SERVER['X-Forwarded-For'] ) ) {
        $ip = $_SERVER['X-Forwarded-For'];
    }

    if ( isset( $_SERVER['HTTP_X_FORWARDED_FOR'] ) ) {
        $ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
    }

    if ( isset( $_SERVER['REMOTE_ADDR'] ) ) {
        $ip = $_SERVER['REMOTE_ADDR'];
    }

    $pos = strpos($ip,":");
    if ($pos === false) {
        return $ip;
    }else{
        return substr($ip,0,$pos-1);
    }
}

Hello,

In my case the site uses WAF and the IP has a port. I think that’s why the error keeps appearing.
