How do I resolve this problem?
Warning: Cannot modify header information - headers already sent by (output started at
It happens when this script is executed:
header('Location: http://plasticsurgery.dir2biz.com') ;

NOTE: Before the IP address of my domain was changed, it worked fine

This means that there is some white (blank) line or some other output to the browser in the page code. This can have nothing to do with the IP change, it is a change in the page code. Would need more info: which page is this (link) ?

Actually, I have several pages with the same problem. But all of them used to work fine before the IP change.
This is one: http://puerto-rico.dir2biz.com
The coding is this:

<?php
session_start();


$ip = $_SERVER["REMOTE_ADDR"];
if ($_POST['verification']<>$ip) {
EXIT("Verification NUMBER failed... go back and retry");
}


if (strlen($_POST['Company'])<3){
$msg=$msg."NAME IS TOO SHORT. VERIFY. GO BACK<BR>";
$flag="NOTOK";
}


if (strlen($_POST['Company'])>40){
$msg=$msg." Name can not be more than 40 characters<BR>";
$flag="NOTOK";
}
//-------------




$company = $_POST['Company'];
$category = $_POST['Category'];
$address= $_POST['Address'];
$telephone = $_POST['Telephone'];
$fax = $_POST['Fax'];
$city = $_POST['City'];
$zip = $_POST['Zip'];
$email = $_POST['Email'];
$url = $_POST['url'];
$date = date('Y-m-d');






$hoy_mas_30= mktime(0,0,0,date("m"),date("d")+30,date("Y"));
$hoy_mas_30=date("Y/m/d", $hoy_mas_30);






//echo sumaDia($hoy,$duracion,$hoy_mas_30);
echo "<br>";






//=== AQUI SE LLAMA EL CONFIG =========
include('config.php');
//==== FIN LLAMADO CONFIG ============

$con = mysql_connect($dbservername,$dbusername,$dbpasswor d);
mysql_select_db($dbname, $con);





mysql_query("INSERT INTO prfaxdir (company,telephone,fax, address,city, zip, email,url, ip,date,category) values ('$company','$telephone','$fax','$address','$city' ,'$zip', '$email','$url', '$ip','$date','$category')");








header('Location: http://puerto-rico.dir2biz.com') ;


mysql_close($con);


?>

I believe your issue is here:

//echo sumaDia($hoy,$duracion,$hoy_mas_30);
echo "<br>";

delete echo "<br>"; or preceed it with //

It causes output to the browser thus creating the issue.

Your are completely right. That was the problem.
Thanks !!
