If your WordPress theme supports widgets, simply add the Defensio Counter widget to your sidebar. You can set color and alignment options.

If your theme does NOT support widgets, all hope is not lost. You can simply edit your 'sidebar.php' file and add the following code snippet where you want the counter to appear:

By default, the counter is dark grey and left aligned. However, you can customize your counter by passing arguments as follow:

You can replace 'color' by 'dark' or 'light' and you can replace 'align' by 'left', 'right', 'center'.

If you are familiar with basic image manipulation, CSS and HTML, you'll find it very easy to create your very own Defensio counter. To do so, you only need to modify lib/defensio_counter.php and put a custom .gif image file in the images directory. Be careful to follow the naming convention we already have in place.


Defensio does not work with WordPress 2.9 due to a known WordPress bug (http://core.trac.wordpress.org/ticket/11505). This bug has been fixed in WordPress 2.9.1, so make sure to update your installation before using Defensio.

PHP 5 is also required. This plugin will NOT work with PHP 4.
