Error fatal al activar plugin  

Hola! A ver si me podeis echar un cable.

Estoy intentando activar Page Generator Pro y me dice que no puede activarlo por un error fatal.

He activado debug y el error que me saca es este:

Deprecated: Creation of dynamic property LicensingUpdateManager::$plugin is deprecated in .../abogadosdivorcios/wp-content/plugins/page-generator-pro/_modules/licensing/lum.php on line 36

¿Sabeis por que puede ser?

Gracias de antemano
