Title: Smart Custom 404 Error Page Author: NerdPress Published: 30 de septiembre de 2013 Last modified: 16 de julio de 2025 --- Buscar plugins ![](https://ps.w.org/404page/assets/banner-772x250.png?rev=3345344) ![](https://ps.w.org/404page/assets/icon-256x256.png?rev=3345344) # Smart Custom 404 Error Page Por [NerdPress](https://profiles.wordpress.org/nerdpressteam/) [Descargar](https://downloads.wordpress.org/plugin/404page.11.4.8.zip) * [Detalles](https://es.wordpress.org/plugins/404page/#description) * [Valoraciones](https://es.wordpress.org/plugins/404page/#reviews) * [Desarrollo](https://es.wordpress.org/plugins/404page/#developers) [Soporte](https://wordpress.org/support/plugin/404page/) ## Descripción Atraer visitantes a tu sitio web requiere tiempo y esfuerzo. Cada visitante es importante. La página de error 404 por defecto de la mayoría de los temas no proporciona ninguna información sobre lo que se puede encontrar en tu sitio. Un visitante primerizo, que no te conoce, se encuentra en un callejón sin salida y abandona tu sitio web.¡ Configura una útil página de error 404 personalizada para mantenerlos en tu sitio! Este práctico plugin te permite crear fácilmente tu propia página de error 404 sin ningún esfuerzo y funciona con casi todos los temas. ### ¡Fuera de la jubilación! NerdPress has adopted Smart Custom 404 Page! [Read the announcement here.](https://www.nerdpress.net/announcing-404-page/) Hemos sido fans de este plugin durante muchos años, y estamos agradecidos por los muchos años de servicio de Peter a la comunidad. Peter se retiró del desarrollo de plugins en octubre de 2023, así que nos hemos puesto manos a la obra para ayudar a garantizar que este plugin siga funcionando bien ahora y en el futuro. ### Uso Crea tu página de error 404 personalizada como cualquier otra página utilizando el editor de WordPress (`Páginas > Añadir nueva`). Luego ve a `Apariencia > Página de error 404` y selecciona la página creada como tu página de error 404 personalizada.¡ Ya está! ### ¿Por qué utilizar este plugin? A diferencia de otros plugins similares, el plugin 404page **no crea redirecciones**. Eso es **bastante importante** porque se entrega un código 404 correcto que indica a los motores de búsqueda que la página no existe y debe ser eliminada del índice. Además, el plugin 404page **no crea peticiones adicionales al servidor**. ### Requisitos El único requisito para este plugin es que cambies la estructura de enlaces permanentes en `Ajustes > Enlaces permanentes` a cualquier otra cosa que no sea «Simple». Esto también activa la gestión de errores 404 de WordPress. ### Bloque y shortcode #### Bloque The Plugin offers a block «URL causing 404 error» for the block-based editor to show the URL that caused the error. The block offers three display options: * «Page» to show the page including path ( e.g. `does/not/exist` ) * «Domain Path» to show the URL without protocol and parameters ( e.g. `example. com/does/not/exist` ) * «Full» to show the complete URL ( e.g. `https://example.com/does/not/exist?p= 1` ) #### Shortcode The Plugin offers a shortcode «pp_404_url» for the classic editor to show the URL that caused the error. There are three possible options: * **`[pp_404_url page]`** to show the page including path ( e.g. `does/not/exist`) * **`[pp_404_url domainpath]`** to show the URL without protocol and parameters( e.g. `example.com/does/not/exist` ) * **`[pp_404_url]`** or **`[pp_404_url full]`** to show the complete URL ( e.g.` https://example.com/does/not/exist?p=1` ) ### Información sobre la privacidad del plugin * Este plugin no establece cookies * Este plugin no recoge ni almacena ningún dato * Este plugin no envía ningún dato a servidores externos ### Para desarrolladores #### Gancho de acción El plugin añade un gancho de acción `404page_after_404` que puedes utilizar para añadir funcionalidad extra. La posición exacta en la que se produce la acción tras detectar un error 404 depende del método operativo. Tu función no debe generar ninguna salida. No tiene parámetros. #### Constante Si el plugin 404page está instalado y activado, define la constante PHP `PP_404`. Comprueba su existencia para detectar el plugin 404page. #### Funciones El plugin proporciona las siguientes funciones: * **`pp_404_is_active()`** to check if there is a custom 404 page selected and the selected page exists * **`pp_404_get_page_id()`** para obtener el ID de la página 404 * **`pp_404_get_all_page_ids()`** para obtener un array de identificadores de página en todos los idiomas * **`pp_404_get_the_url( $type )`** para obtener la URL que causó el error 404 - Parameter $type string Optional - «page» to get the page including path ( e.g. `does/not/exist` ) - «domainpath» to get the URL without protocol and parameters ( e.g. `example. com/does/not/exist` ) - «full» (default) to get the complete URL ( e.g. `https://example.com/does/ not/exist?p=1` ) #### Modo nativo If you are a theme developer you can add native support for the 404page plugin to your theme for full control. ## Bloques Este plugin proporciona 1 bloque. * URL causing 404 error ## Reseñas ![](https://secure.gravatar.com/avatar/f718cef9735ef93435481b23cf4cd6b92d1d4a65eaec72c73827e2a1344b24f4? s=60&d=retro&r=g) ### 󠀁[Great 🙂](https://wordpress.org/support/topic/great-17098/)󠁿 [meeresschutz](https://profiles.wordpress.org/meeresschutz/) 12 de abril de 2026 Does the job just fine, simple and easy. ![](https://secure.gravatar.com/avatar/894c5dbfdb56f6ed18c33b79e028a791cbd5d45448fff583d87ebbcde6032258? s=60&d=retro&r=g) ### 󠀁[mooolt bo](https://wordpress.org/support/topic/mooolt-bo/)󠁿 [deadko](https://profiles.wordpress.org/deadko/) 5 de marzo de 2026 molt útil, abans tenia perduda la pagina ![](https://secure.gravatar.com/avatar/965d31300afc6a2a298767c962cf3152f20a748403508ad58877ef778ff17cab? s=60&d=retro&r=g) ### 󠀁[Indispensabile ed Ottimo plugin](https://wordpress.org/support/topic/indispensabile-ed-ottimo-plugin-2/)󠁿 [bigportal](https://profiles.wordpress.org/bigportal/) 17 de diciembre de 2025 Semplice e funzionale ![](https://secure.gravatar.com/avatar/f3b7bc9f4d6e747c5db925f48f6e50163485da773b00b2aacc1486ac9ee962f3? s=60&d=retro&r=g) ### 󠀁[Great plugin!](https://wordpress.org/support/topic/great-plugin-40808/)󠁿 [Veru](https://profiles.wordpress.org/beautysveru/) 2 de septiembre de 2025 I am satisfied with the plugin. ![](https://secure.gravatar.com/avatar/b94e2b2546b8ceb0637a68a2ea522c1dcd9ff376bd944a1c3e186263223466f6? s=60&d=retro&r=g) ### 󠀁[Gorgeous](https://wordpress.org/support/topic/gorgeous-36/)󠁿 [panon](https://profiles.wordpress.org/panon/) 19 de agosto de 2025 Awesome.
