No me refiero a eliminarlos de la plantilla para que no puedan comentar, ni siquiera a desactivarlos desde los ajustes de WordPress, me refiero a eliminar completamente los comentarios y cualquier referencia, incluso visual, a su existencia.

Está claro, los comentarios son parte de los blogs, esencia misma de la Web 2.0, pero hay ocasiones en que - sobre todo para trabajos a clientes - en que es posible que quieras quitar cualquier atisbo de que tal cosa siquiera existe.

En este raro, pero probable, caso, Frank ha elaborado un plugin cuyo código quita toda referencia a los comentarios, vamos, que dejan de existir en tu WordPress, no verá rastro ni cita alguna a los mismos.

Solo tienes que guardar este código con el nombre que quieras, subirlo a la carpeta 'plugins' de tu instalación de WordPress, activarlo y habrás eliminado totalmente los comentarios de tu WordPress.
