¡Esto es exactamente lo que quiero! Solo quiero bloquear la vista pública antes de que el sitio esté listo. No necesita otras funciones. ¡Muchas gracias por hacerlo simple!

Plugin super simple pero muy funcional.

Simple et efficace

perfect fit for my needs.
so rare to find lightweight plugins.
even needs no configuration.
goodby "Members" plugin >.<

so rare


So simple and so clever! As a plugin developer, a big part of my job is creating admin settings screens. So I spent a good few minutes trying to find the settings screen to fully enable this plugin. Then it dawned on me, there wasn't one. You just install, and the rest of the world is locked out. Genius! Fantastic work Kevin.Ben Roberts


Absolutely Perfect
