Hallo Zusammen,

ich verwende Typo3 6.2.25 LTS auf Ubuntu 14.04 und Apache2, PHP 5.5.

Nach der Anmeldung im Backend als Administrator versuchte ich Install Tool zu starten.
Das richtige Password, das auch in der LocalConfiguration.php hinterlegt ist, habe ich dort eingegeben.
Leider macht die Seite nur ein Refresh und zeigt mir wieder die Loginmaske (siehe Anhang "Install Tool After Login.png" )
Das Install Tool kann schon mal im Verzeichnis "typo3conf" die Datei "ENABLE_INSTALL_TOOL" anlegen, das ist schon mal gut. Aber weiter will es nicht machen :(

In der access.log von Apache2 steht folgendes:

Hatte schon mal jemand Erfahrung mit so einem Problem?
Kann mir bitte jemand weiterhelfen, woran könnte es liegen?
Liegt es evtl. an der Konfiguration, falls ja an welcher?

Besten Dank.

Schöne Grüße
