How To: Fixing Popularity Contest Plugin for WordPress 2.5

The problem(s): With some upgrades of the WordPress 2.5 branch, the Popularity Contest WordPress plugin is not working properly. Also, people trying to activate the Popularity Contest plugin on a brand new WordPress install are getting a fatal error or a “doesn’t exist” message when attempting to activate the plugin.

The solution(s): I actually ran into this problem on a fresh install of WordPress. After several attempts, I was unable to figure out the problem myself. Thankfully, a quick Google search showed a post over at WPGuy which gave details on fixing both problems!

Here is what you need to know if you have this problem:

Fix problems with the upgrade to WordPress 2.5

Open your Popularity Contest plugin (edit it) and search for this code:

require('../../wp-blog-header.php');

And replace it with this:

require('../wp-blog-header.php');

Fix problems with a new install of WordPress 2.5

In addition to doing the above, you need to search for the following code:

if (isset($_GET['activate']) && $_GET['activate'] == ‘true’) {

And replace it with this:

if (isset($_GET['action']) && $_GET['action'] == ‘activate’) {

I went through both of these steps on my fresh WordPress install and it fixed the problem perfectly!
