[TYPO3-UG Italy] Errore su vecchia installazione HELP

[mario chiari]

Salve a tutti

improvvisamente una vecchia installazione di TYPO3, su  un server su cui
ho poco controllo, è saltata, credo per un upgrade di php. 
A http://nomedominio/typo3/index.php ricevo la  prima lista di errori di
cui sotto.  Grato di un hint per ristabilire il funzionamento
velocemente. 

grazie ciao
mario
