Le code fonctionne parfaitement sur le serveur localhost xampp mais ne fonctionne pas sur Cpanel Je pense que la commande sesion_start ne fonctionne pas. Si je me connecte en utilisant mot de passe incorrect alors il affiche une erreur de son code php moyenne dans LoinPage.php wroks mais quand j'entrer le nom d'utilisateur et mot de passe, il affichera la page blanche au lieu de me prendre à AdminDashboard.php
LoginPage.phppage de connexion le code php ne fonctionne pas sur cpanel la page vierge vient après le login succefull

On dirait que vous mixez JavaScript (alerte) avec PHP. Rappelez-vous que header() doit être appelé avant que toute sortie réelle ne soit envoyée, soit par des balises HTML normales, soit par des lignes vides dans un fichier, soit par PHP. Header ne fonctionnera pas si vous avez envoyé quelque chose au client avant cette déclaration. –
