Hola a tod@s,
creo que el problema estaba en el tamaño de fichero de upload configurado en el panel php del hosting de arsys.
He subido el tamaño y el timeout a 60 segundos (no me deja subirlo a más)
Ahora el script actualiza pero tira este error:
Código:

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
