“Plugin could not be activated because it triggered a fatal error.”
This is the error I had when I activated Popularity Contest for my a new blog of mine using Wordpress 2.6.1. I had this similar problem with Popularity Contest the previous time and it is due to the condition to make some tables in your SQL.
Here is an easier fix
Go to line 59
Find
require('../../wp-blog-header.php');
Replace with
require('../wp-blog-header.php');
Go to line 1528
Find
if (isset($_GET['activate']) && $_GET['activate'] == 'true') {
Replace with
if (isset($_GET['action']) && $_GET['action'] == 'activate') {






Hi, I found this other one http://www.guatewireless.org/popularity-contest-14-wordpress-26-plugin-fixed-and-hacked/
Its a pop-contest version that its already wp 2.6.1 ready, on the other hand I search and cant find the if condition you wrote about.
