Enviar mensaje queda pagina en blanco

[den_22]

Hola, cambié un par de cosas, me dice "Tu mensaje se ha enviado a usuario" , pero no me lo inserta en la base de datos.

Código PHP:

<?php
 error_reporting(E_ALL ^ E_NOTICE);
session_name('pLogin');
session_set_cookie_params(2*7*24*60*60);
session_start();
include("connect.php");
include("date_time_format.php");
 
$id=$_SESSION['id'];
$usuario=$_SESSION['usuario'];
$from_mem=$_SESSION['id'];
 
 
 
$tid=$_REQUEST["id"];
$fid=$_SESSION["id"];
 
$to_mem=mysql_fetch_array(mysql_query("select * from members where id=$tid"));
$from_mem=mysql_fetch_array(mysql_query("select * from members where id=$fid"));
 
 
            if (!get_magic_quotes_gpc()) {
            $message=str_replace('$', '\$',addslashes($_REQUEST["message"]));
            $subject=str_replace('$', '\$',addslashes($_REQUEST["subject"]));
            }
            else
            {
            $message=str_replace('$', '\$',$_REQUEST["message"]);
            $subject=str_replace('$', '\$',$_REQUEST["subject"]);
            }
 
        
mysql_query ("Insert into `dm_messages` ( dm_fid , dm_tid , dm_message , dm_subject , dm_msg_read,d_f_del,d_t_del,  dm_onstamp) VALUES ( $fid,$tid,'$message'," ."'$subject'" .",'No','No','No','" .date("YmdHis",time())."')");
 
 
 
    
 
//Gets member info
    $sql = "SELECT max(dm_id) FROM dm_messages" ;
    $rs_query=mysql_query($sql);
    $rs=mysql_fetch_array($rs_query);
    $id=$rs[0];
    
    $rs0=mysql_fetch_array(mysql_query("select *,UNIX_TIMESTAMP(dm_onstamp) as ondate  from dm_messages where dm_id=" .$id));
    $rs1=mysql_fetch_array(mysql_query("select * from members where id=" .$rs0["dm_tid"]));
    $rs2=mysql_fetch_array(mysql_query("select * from members where id=" .$rs0["dm_fid"]));
    $ondate=dm_date($rs0["ondate"]);

            $body=str_replace("%signup_url%",$sb_null_char,str_replace("%login_url%",$login_url,$body));

    //die();
                if( $rs["sb_status"]=='yes')
                     mail($to,$subject,$body,$header);
 
          }// end if status is on
 
         
      }
    $errmsg="Tu mensaje ha sido enviado a  ".$to_mem["usuario"];
