Important Problemas al actualizar de 1.7.2 a 2.0.4

Buenas, he decidido actualizar mi foro de la version 1.7.2 a la 2.0.4, y me he encontrado los siguientes problemas:
No me aparecen los ultimos mensajes posteados en el modulo latests, el modulo estadisticas no las da correctamente, ya que dice que el post mas visto tiene 89 visitas, y hay posts con 200k+.

Tambien cuando entro en Ultimas Discuciones en el propio menu del foro, no aparecen los ultimos posts creados.

Saludos
