"Older Posts" (page 2) Gets me 404 Error

Hello,

On my blog (www.zylblog.info), when I click to go to read older posts, I get a 404 error message.
The link “Older Posts” goes to on the homepage is http://zylblog.info/wordpress/?paged=2
If I browse individual categories, I can look at older posts in a category, but not older posts from the home page.

I disabled WP-SuperCache to make sure it was not causing the problem, and I also did an automatic reinstall to no avail.
