Why you should choose 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. A redirect would result in a HTTP code 301 or 302 and the URL would remain in the search index.
  • Different from other similar plugins the 404page plugin does not create additional server requests.

Action Hook

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.

FAQ

Are there any requirements?

To enable the WordPress 404 error handling you have to set the Permalink Structure (‘Settings’ -> ‘Permalinks’) to anything else but ‘Default’. Otherwise 404 errors are handled by the webserver and not by WordPress.

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.

Reviews

Works smoothly but…

On my installation (current with TwentyFourteen) it works fine, but inhibited iTheme Security’s 404 error logging.
With a simple 404 log this would be no problem.

Great

Simple and easy to use. Great for my need.
