Mi segnala questo errore

Fatal error: Cannot redeclare get_youtube_id() (previously declared in /membri/znetitaly/wp-content/plugins/jetpack/functions.compat.php:22) in /membri/znetitaly/wp-content/plugins/shortcodes/modules/youtube.php on line 111

Ho aggiornato questo mattina alla nuova versione di wordpress.
Quindi dal meno wordpress ho aggiornato solo i plugin ritenuti compatibili con la versione attuale.

A metà aggiornamento è apparsa la pagina in questo modo.
Non riesco ad accedere neanche al menù operativo.

Non ho toccato nulla ma
Andando a interrogare il file function compat nella directory trovo quanto segue:






<?php

Idee?

Grazie.
