Fantástico plugin para conocer todo sobre tu instalación de WordPress y tu servidor. Imprescindible en muchas ocasiones.

No es un plugin para tener siempre activo, pero sí para tenerlo siempre instalado y revisar la información cada poco tiempo, antes de actualizaciones, para comprobar requisitos, estado de la memoria del servidor y mucho más.
