error 500 con php

[rajoycalidade]

Acaban de actualizar el servidor donde alojo una web pero ahora tengo error 500 en todas las paginas. He revisado el archivo log de errores y veo varias lineas:

[11-Jan-2018 09:32:38 Europe/Madrid] PHP Fatal error: Directive 'register_globals' is no longer available in PHP in Unknown on line 0

¿me puden ayudar a resolverlo? gracias
