Probleme creation site web joolma

Salut,
Fait un copier/coller des lignes 20 ici.

<head>
<title><?php echo $mosConfig_sitename; ?> - Administration [Joomla!]</title>
<link rel="stylesheet" href="templates/joomla_admin/css/template_css.css" type="text/css" />

Il me semble que cela doi etre cela la

Ce n'est pas ces lignes là apparemment : il n'y a aucune erreur.

Ca pourrait etre celle ci mais je ne l'ai pas toucher

"if (!file_exists( '../configuration.php' )) {
header( 'Location: ../installation/index.php' );
exit();
}

require( '../globals.php' );
require( '../configuration.php' );

// SSL check - $http_host returns <live site url>:<port number if it is 443>"

Remplace la dernière ligne "// SSL check ..." par celle-ci :

echo "// SSL check - $http_host returns <live site url>:<port number if it is 443>";

J'ai comme di précedament, mais cela me marque toujours le même problème

Ben passe le fichier index.php complet

Voila, merci de se donner au temps de mal :

Bizarre, chez moi, il n'y a aucun problème.
Refait une nouvelle installation (en retéléchargeant les fichiers).
Le echo que je t'ai fait ajouter, c'est une erreur de ma part.Donc tu peux le retirer tout ce qu'il y a avant //

Je crois que c'est la meuilleur solution
Merci de ton aide
J'écrirai l'évolution négative ou positive de mon problème.

Finalement j'ai réussi, merci pour la suggestion de réinstaller les fichiers posant problèmes.
