Impossibile amministrare il sito dopo aggiornamento WP

[marcomiserini]

Salve.

Ho appena effettuato l'aggiornamento del mio blog all'ultima versione di WP.
Il blog sembra funzionare perfettamente (http://marcomiserini.altervista.org) ma se vado in Amministra sito (quindi anche per la creazione di nuovi articoli) mi vengono restituiti una serie corposa di errori, che riporto -in parte- qui sotto.
Qualcuno sa come risolvere il problema?

Grazie,
Marco

[marcomiserini]

Ho risolto.

Il problema era il plugin Jetpack. Disabilitato (modificando il nome della directory del plugin) e riaggiornato.
Ora funziona di nuovo tutto.
