Custom Montezuma 404 page

No need for a 404 plugin. With MZ, simply make your own main template 404.php, copying something like page.php.

In the content div, put something like "404 Page Not Found" between the <h1> tags and remove everything else between those tags.

In the post-bodycopy div, put your custom message (you'll need to use <p> tags) and remove everything else. Links to your home page, search page, site map, last post, and/or whatever you want can be included.

Save the template. To test it, simply enter a nonexistent page url of your site into your address bar.

Here's the official WP codex doc.

As an example, here's what I put up for now:

My main menu, with a link to my home page is in the sidebar. I'll add a link to a site map after I make one.

It's possible I could have stripped out more code from the template to make it more elegant, but I didn't dig into what that would do.

If you want this to be a 'How To:' give a step by step guide with examples and edit your explaination to be clear. in your second line you state
The you start talking about the post-bodycopy div, but in the previous statement you said to remove everything else from the content div. I know what you meant to say, but it's not what you said.

Thanks jerryc
