Question

I get that error from chrome (all the other browsers appear blank), the problem is that, I cant see the error.. I have got a lot of code on my page, and I dont seem to find what caused the error.. could you help me?!?! cause i dont know why it is caused

I get it from my php code and i am using dreamweaver.

This is how my connection is defined:

   <?php
# FileName="Connection_php_mysql.htm"
# Type="MYSQL"
# HTTP="true"
$hostname_QASite = "localhost";
$database_QASite = "qasite";
$username_QASite = "root";
$password_QASite = "";
$QASite = mysql_connect($hostname_QASite, $username_QASite, $password_QASite) or trigger_error(mysql_error(),E_USER_ERROR); 
?>

    if ((isset($_POST['topic_id'])) && ($_POST['topic_id'] != "")) {
  $deleteSQL = sprintf("DELETE FROM topic WHERE topic_id=%s",
                       GetSQLValueString($_POST['topic_id'], "int"));

  mysql_select_db($database_QASite, $QASite);
  $Result1 = mysql_query($deleteSQL, $QASite) or die(mysql_error());
}

some of the other php code:

if ((isset($_POST['sub_topic_id'])) && ($_POST['sub_topic_id'] != "")) {
  $deleteSQL = sprintf("DELETE FROM sub_topic WHERE sub_topic_id=%s",
                       GetSQLValueString($_POST['sub_topic_id'], "int"));

  mysql_select_db($database_QASite, $QASite);
  $Result1 = mysql_query($deleteSQL, $QASite) or die(mysql_error());

  $deleteGoTo = "/QASite/Admin/main.php";
  if (isset($_SERVER['QUERY_STRING'])) {
    $deleteGoTo .= (strpos($deleteGoTo, '?')) ? "&" : "?";
    $deleteGoTo .= $_SERVER['QUERY_STRING'];
  }
 // header(sprintf("Location: %s", $deleteGoTo));
}

mysql_select_db($database_QASite, $QASite) or die(mysql_error());

// FUNCTIONS THAT INSERT AND MODIFY THE TOPICS
if(isset($_POST['update_topic']))
{
    UpdateTopic();
}
else if(isset($_POST['insert_topic_submit']))
{
   InsertSubTopic();
}
else if(isset($_POST['update_sub_topic']))
{

    UpdateSubTopic();
}
else if(isset($_POST['insert_topic']))
{
    InsertTopic();
}

Make sure PHP is configured to display errors. Also, check the PHP error log.
