I have a couple issues going on. I switched themes and now I can’t get this to work. I assume its the jquery issue but I can’t find it. I created a test contest for your review. Its located at http://www.averagehunter.com/2013/07/test-contest/ the password is “contesthopper”

Another issue I have is that the script creates a blank contest every couple hours on its own. Every day I go into the plugin and delete a dozen or more blank ACTIVE contests.

Thanks.
Matt
