My earlier post on the generator metatag problem (which shows the WordPress version on the Internet) includes a simple solution – one line of code in your theme.

However, it’s not always the best solution:

• If you move between themes a lot, keeping track of which ones are ‘leaking’ security info can be annoying.
• Editing each of theme can add up as well.
• If you don’t want to edit a theme (for instance, you are using ABTheme), then another solution would be better.

That other solution of course is to wrap the line into a plugin, like this:

<?php
/*==============================================================================
Plugin Name: utopia51/Kill Generator Metatag in WordPress Page Header
Author: David Pankhurst
Version: 1.00
Author URI: http://ActiveBlogging.com/
Description: Removes the generator metatag showing the WordPress version from your theme
Plugin URI: http://activeblogging.com/info/wordpress-plugin-how-to-kill-version-generator-metatag
==============================================================================*/
static $utopia51_once=0;
if ($utopia51_once++<1)
  remove_action('wp_head','wp_generator');
//------------------------------------------------------------------------------
?>

You can download it in the plugins section (utopia51, ‘Fix Meta Version Tag’).

Just drop the utopia51.php plugin file in your /wp-content/plugins/ directory, and activate – the result is your theme will no longer show your version!
