Merhaba arkadaşlar ben PHP de bir blog scripti kodluyorum. Böyle bir hata çıkıyor çözümünü bulamadım yardımcı olursanız sevinirim.

<?php include "header.php" ?>
<div class="main-container container pt-24" id="main-container">
<div class="row">
<div class="col-lg-8 blog__content mb-72">

<!-- Son Yazılar -->
<section class="section">
<div class="title-wrap title-wrap--line">
<h3 class="section-title">Son Yazılar</h3>
<!-- <a href="#" class="all-posts-url">Tümü</a>
--> </div>


<?php

$sayfa = intval($_GET["sayfa"]); if(!$sayfa || $sayfa < 1){$sayfa=1;}
$yazi_say = $db->query("SELECT * FROM yazilar");
$ToplamYazi = $yazi_say->rowCount();
$limit = 8;
$sayfasayisi = ceil($ToplamYazi/$limit); if($sayfa > $sayfasayisi){$sayfa=$sayfasayisi;}
$goster = $sayfa * $limit - $limit;
$gorunensayfa = 3;

$yazilar = $db->prepare("SELECT * FROM yazilar
INNER JOIN kategoriler ON kategoriler.kategori_id = yazilar.yazi_kategori_id
ORDER BY yazi_id DESC LIMIT $goster,$limit");
$yazilar->execute();
$yazi_listele = $yazilar->fetchALL(PDO::FETCH_ASSOC);

foreach ($yazi_listele as $row) { ?>
