kristifof on "Disqus plugin"

Hello,

I'm new to using Wordpress and am working on starting a blog. I downloaded the Disqus plugin to use for comments, but noticed that when I put my first post up, there isn't an area at the end to comment.

Also, there is a link under the title that says comment, but when I click on it to test it, it takes me to an error page.

Any tips on how to fix these issues?
