404page – your smart custom 404 error page

Popis

With 70,000+ active installations the 404page plugin is the most used plugin to create a customized 404 error page in WordPress.

It allows you to easily create your own 404 error page without any effort and it works with almost every theme.

If you like this plugin please do me favor and leave a review here on wordpress.org so that other people know it is helpful for you. Thanks!

Usage

Create your custom 404 error page just like any other page using the WordPress Page Editor. Then go to ‚Appearance‘ -> ‚404 Error Page‘ and select the created page as your custom 404 error page. That’s it!

Why use this plugin?

Different from other similar plugins the 404page plugin does not create redirects. That’s quite important because a correct code 404 is delivered which tells search engines that the page does not exist and has to be removed from the index.

Different from other similar plugins the 404page plugin does not create additional server requests.

Requirements

The only requirement for this plugin is that you change the Permalink Structure in ‘Settings’ -> ‘Permalinks’ to anything else but ‘Plain’. This also activates the WordPress 404 error handling.

For developers

Action Hook

The plugin adds an action hook 404page_after_404 which you can use to add extra functionality. The exact position the action occurs after an 404 error is detected depends on the Operating Method. Your function must not generate any output. There are no parameters.

Native Support

If you are a theme developer you can add native support for the 404page plugin to your theme for full control. Read more.

Časté dotazy

Will it work with the theme I’m using?

This plugin is designed to work with as many themes as possible. It uses the WordPress Template System to detect and handle 404 errors. If your theme makes use of this Template System this plugin will work properly. If it does not the plugin offers a so called Compatibility Mode, which uses its completely own method to detect and handle 404 errors. If this plugin does not work properly, try to activate Compatibility Mode.

Are 404 errors redirected?

No, there is no redirection! The chosen page is delivered as a ‚real‘ 404 error page. This results in a HTTP 404 code and not in 301 or 302, which is important for Search Engines to tell them, that the page does not exist and should be deleted from the index.

Is it possible to add custom CSS to the 404 page?

The 404page plugin adds a CSS class error404 to the <body> tag which can be used for extra styling.
