paginador con php solo muestra registros en 1ra pagina? :C 
aca les dejo el código a ver si me ayudan a encontrar el fallo que se que mucha gente aca tiene experiencia y un muy buen ojo...
Código PHP:
<!-- PHP PARA LA PAGINACION -->
<?php
/*
Place code to connect to your DB here.
*/
include("php/conexiondb.php"); // include your code to connect to DB.
$tbl_name="post"; //your table name
// How many adjacent pages should be shown on each side?
$adjacents = 2;
/*
Primero obtenemos el numero total de filas en la tabla.
*/
$query = "SELECT COUNT(*) as num FROM $tbl_name";
$total_pages = mysql_fetch_array(mysql_query($query));
$total_pages = $total_pages['num'];
/* variables a utilizar para la consulta. */
$targetpage = "etiquetas.php"; //nombre del archivo
$limit = 2; //Cantidad limite de registros a mostrar por cada pagina
$page = "http://localhost/blog/etiquetas.php";
if(isset($_GET["page"])){
$page = (int)$_GET["page"];
$start = ($page - 1) * $limit; //primer item a mostrar
}else{
$start = 0; //Si no hay registros existentes, empezar pagina en 0
}
/* Realizamos y obtenemos datos de la consulta. */
$sql = mysql_query("SELECT * FROM $tbl_name ORDER BY id DESC LIMIT $start, $limit");
//$result = mysql_query($sql);
/* Setup page vars for display. */
if ($page == 0) $page = 1; //if no page var is given, default to 1.
$prev = $page - 1; //previous page is page - 1
$next = $page + 1; //next page is page + 1
$lastpage = ceil($total_pages/$limit); //lastpage is = total pages / items per page, rounded up.
$lpm1 = $lastpage - 1; //last page minus 1
/*
Now we apply our rules and draw the pagination object.
We're actually saving the code to a variable in case we want to draw it more than once.
*/
$pagination = "";
if($lastpage > 1)
{
$pagination .= "<div class=\"pagination\">";
//previous button
if ($page > 1)
$pagination.= "<a href=\"$targetpage?page=$prev\"> <span class=\"icon-reply\" alt=\"Atras\"> </span></a>";
else

# $pagination.= "<span class=\"disabled\">« previous</span>";
//pages
if ($lastpage < 7 + ($adjacents * 2)) //not enough pages to bother breaking it up
{
