Older Posts Button Not Working

Hey All-

My site’s URL is: http://www.derangeddiaries.com

When I click the Older Posts at the bottom of the page, it displays the same posts. Doesn’t go any older.

The url it “goes to” is:
http://www.derangeddiaries.com/page/2/

I think it’s an issue with the loop? Unsure. Would appreciate your help!
