Fatal error after updating to 3.0

Hello Sujin,

First of, I’m absolutely love your plug-in and I’m very happy to see that you’re working hard on updating it!

However, after updating to 3.0, if you click on one of the tags in the cloud i get this error:

Fatal error: Call to a member function is_main_query() on a non-object in /var/www/web142/html/wp-content/plugins/2d-tag-cloud-widget-by-sujin/functions.php on line 69

Just thought I’d post it here so you can check it out: http://www.i11u.com/blog/
