Hola a todos/as,
Estoy intentando restaurar un curso instalado en un entorno MOODLE versión 3.0 a una plataforma MOODLE 3.5.2, pero cuando restauro la copia de seguridad en la plataforma de destino me aparece el siguiente error:
Parece ser que está duplicando un registro en bbdd que esta referenciado de forma única en un índice. Pero no sé cómo solucionarlo.
