Problema con Joomla e Phpmyadmin

Ciao a tutti, non so come fare ad installare phpmyadmin nel mio spazio web di altervista.
Ho caricato tutto il pacchetto che ho scaricato dal sito di phpmyadmin, ma quando vado ad iniziare l'installazione mi compare un errore con scritto:
Non posso far partire la sessione senza errori, controlla gli errori nel log di PHP e/o del tuo server web e configura correttamente la tua installazione di PHP.

Come devo fare x installare phpmyadmin, creare un db e buttargli dentro i file di joomla?

Grazie mille ...

Non hai bisogno di installarlo, AV lo ha già, basta andare nella sezione tools del tuo pannello di controllo.

PS: prima di tutte queste operazioni devi attivare il database, per maggiori info fai qualche ricerca nel forum.


Ciao!

Eccola:

Scarichi il pacchetto dal sito ufficiale (mi raccomando, una versione stabile), al suo interno dovrebbero esserci le istruzioni.
In teoria dovresti configurare il file di, appunto, configurazione, indicando i dati di connessione al database, e caricando il tutto dovrebbe iniziare a funzionare.


Ciao!

Posta la configurazione personalizzata (omettendo eventuali password).

Posto di seguito parte del file di configurazione della mia installazione personalizzata di phpmyadmin qui su AlterVista.

Premetto col dirti che sicuramente ci sarà un altro metodo (e sicuramente più professionale)...ma almeno così parte...
1) Apri il file session.inc.php in phpmyadmin/libraries
2) cerca

if (! isset($_COOKIE[$session_name])) {
    // on first start of session we will check for errors
    // f.e. session dir cannot be accessed - session file not created
    ob_start();
    $old_display_errors = ini_get('display_errors');
    $old_error_reporting = error_reporting(E_ALL);
    ini_set('display_errors', 1);
    $r = session_start();
    ini_set('display_errors', $old_display_errors);
    error_reporting($old_error_reporting);
    unset($old_display_errors, $old_error_reporting);
    $session_error = ob_get_contents();
    ob_end_clean();
    if ($r !== true || ! empty($session_error)) {
        setcookie($session_name, '', 1);
        PMA_fatalError('strSessionStartupErrorGeneral');
    }
} else {
    @session_start();
} 

3) sostituisci con:

$_COOKIE[$session_name]="prova";
if (! isset($_COOKIE[$session_name])) {
    // on first start of session we will check for errors
    // f.e. session dir cannot be accessed - session file not created
    ob_start();
    $old_display_errors = ini_get('display_errors');
    $old_error_reporting = error_reporting(E_ALL);
    ini_set('display_errors', 1);
    $r = session_start();
    ini_set('display_errors', $old_display_errors);
    error_reporting($old_error_reporting);
    unset($old_display_errors, $old_error_reporting);
    $session_error = ob_get_contents();
    ob_end_clean();
    if ($r !== true || ! empty($session_error)) {
        setcookie($session_name, '', 1);
        PMA_fatalError('strSessionStartupErrorGeneral');
    }
} else {
    @session_start();
} 

Ricorda che il file config.inc.php deve essere in phpmyadmin...

Ciao

ho anche io lo stesso problema...

"Cannot start session without errors, please check errors given in your PHP and/or webserver log file and configure your PHP installation properly."

ma questa modifica non lo risolve..

Sei sicuro di aver modificato correttamente il file config.inc.php* e averlo messo nella cartella principale di phpmyadmin?
Le impostazioni fornite da probid dovrebbero andar bene...
Usa il metodo di autenticazione http per ora...

*nel post precedente ho sbagliato, correggo subito!

Ciao

infatti adesso funziona tutto,
grazie.
