Eliminar completamente los comentarios

Publicado por Fernando Tellado el 7 Jun, 2011

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.

Lo que hace el plugin es lo siguiente:

Cierra todos los formularios de comentarios existentes
Quita los widgets relacionados con comentarios en el editor
Quita todos los enlaces a la gestión de comentarios de los menús de WordPress
Quita la columna de comentarios del Escritorio
Quita los ajustes de comentarios

Aquí tienes unas capturas de como queda de solito y desolado WordPress sin comentarios. Ahora tu decides, igual para algún proyecto te viene bien.

AVISO: esta publicación es de hace dos años o más. Si es un código o un plugin podría no funcionar en las últimas versiones de WordPress, y si es una noticia podría estar ya obsoleta. Luego no digas que no te hemos avisado.
