Custom 404 Pro


IMPORTANT: Please open issues on Github. I will not be using the support area.

Allows users to replace the default 404 page with a custom page from the Pages section in the Admin Panel. Or you can specify a complete URL to redirect on 404.


  • Full 404 Page Control
  • Record 404 Page Data
  • Custom Page Redirect
  • Custom URL Redirect
  • Record Visitor Keywords that led to 404
  • Custom Log Filters
  • Clean code
  • Awesome support

How does it work?

  • WordPress Page: Choose a custom page from the Admin Panel
  • URL: Enter a custom URL for 404
  • Stats: List of all 404s


  • Activate the plugin from the WordPress Admin Panel
  • 404 Logs
  • Global Settings


  • Extract the downloaded ZIP file.
  • Copy the custom-404-pro folder to the wp-content/plugins directory.
  • Activate from the Plugins Section.

Great plugin.

Does exactly what I need it to; custom URL redirect for all 404 pages. Logging is turned off now by default which is great. Excellent little plugin.

Lots of PHP errors in the logs

Come on guys, clean it up. Do some error handling.

Undefined index: c4p_log_redirect_to in /var/www/ on line 167

Works well

Exactly what i was looking for (404 redirect to another URL) and works well.

Google penalized me because of this plugin

This plugin made Google penalize me , my website no longer appears in google search at the moment.

The plugin was working smoothly until google sent me an email because of a page (c4p_log/log-130/) this plugin created .

Incorrect hreflang implementation on *my website**
Google has detected that some pages on your site have implemented the rel-alternate-hreflang tag incorrectly. In particular, there seems to be a problem with incorrect language and region codes, or incorrect bi-directional linking (if page A links with hreflang to page B, there must be a link back from B to A as well). Google uses the hreflang attributes to serve the correct language or regional URL to the right users in search results.

Until you correct the errors on the hreflang links, your website will not benefit from additional language or region targeting.
