Warning: Cannot modify header information - headers already sent by (output started at /home/mysite/admin/lib/debug.php:25) in /home/mysite/admin/lib/sqladmin.php on line 636

/home/mysite/admin/lib/debug.php file below:

<?php


// dependencies


/**
* description
*
* @param
*
* @return
*
* @access
*/
function PrintR($array , $die = false) {
    echo "<table><tr><td><pre style=\"background-color:white\">";
    print_r($array);
    echo "</pre></td></tr></table>";

    if ($die)
        die();
}


/**
* description
*
* @param
*
* @return
*
* @access
*/
function Debug($array , $die = false) {
    if ($_SERVER["REMOTE_ADDR"] != "127.0.0.1") {
//      return "";
    }

    PrintR($array , $die);
}




?>

To make it easier: /home/mysite/admin/lib/sqladmin.php on line 636

header("Location:" . $this->templates["generic_form"]->blocks["Temp"]->Replace(array_merge($_GET,$_POST)));
                            exit;

Answer 1

The header function expects nothing to be outputted before it is ran. By printing the arrays like you did or echoing an error from the debug.php file (which seems to be the case here), that means the output is being written, and this will create a conflict for the header. Try removing it.
