Problem with links to old pages

I have upgraded my blog (www.ipod-tracker.com) to the latest version of WP.

However, I have a problem with links to previous posts. Links like the following are all broken. Check it out:

https://www.ipod-tracker.com/page/2/

This should obviously take me to page 2, which would list posts 11 – 20 … but it doesn’t.

How can I fix this?

Thanks for your help. ??
