GroupOffice-Installation schlägt fehl - MariaSQL?

[mautz001]

Hey Leute,

ist mein erster Post hier, bin seit 1 Monat ca. begeisterter Synology-Besitzer.
Versuche nun gerade auf meine DS213j (DSM 5.0) GroupOffice zu installieren. Nachdem ich anfänglich andauernd einen "could not create /tmpcache"-Fehler hatte, den ich mit einem Eintrag in die config.php behoben habe, bekomme ich nun folgende Fehlermeldung beim Versuch, mich das erste mal anzumelden:

}

Weiß jemand zufällig etwas damit anzufangen? Soweit ich das richtig lesen kann, scheint MariaSQL ja eines der Kommandos nicht korrekt zu interpretieren...
Danke schonmal jetzt für jede Hilfe!
