Erreur Accès site après changement mdp BDD Hebergeu

Bonjour,

Tu dis :

on a changé les mots de passe de l'hebergeur et myphpadmin et maintenant on a cette erreur

Il suffit donc de renseigner les bons identifiants dans tes scripts php ..

Informations à changer, donc, dans un des deux fichiers

  include_once("includes/name_configaration.php");
    /* This is for includeing the all predefine name of database,tables,user,password */
    include_once("includes/connection.php");
    /* This is for includeing the all database connection*/

PS : Habituellement, les commentaires se placent AVANT les lignes de code concernées.. pas après...
