Custom 404 Error Page Plugin. If you’ve been blogging for a while, chances are you’ve moved things around a little. Perhaps you’ve moved things around a lot – and as a result, users are bound to encounter the dreaded 404 error page quite frequently.
Instead of displaying a lame “Page not Found” message, the Custom404 WordPress plugin allows you to display your own custom message, redirect to another WordPress page, or redirect to any external site you want. Recycle your traffic instead of wasting it with a regular 404 page!
Custom404 is easy to use. All you need to do is activate the plugin and put in a simple code into your current 404 page template.
