Okay, so I downloaded the killer Cutline theme created by Chris Pearson, and was having trouble with the Archive and About links.  By trouble, I mean they were not working.

I found out why here.

The header code was constructed under the assumption that your permalink structure ends with the post name (for more info, read this section of the WordPress Codex). Unfortunately, the WordPress default permalink structure is not constructed this way. Thus, whenever someone who is using the default permalink structure attempts to use the links in the navigation menu, they will encounter this problem (i.e. their links won’t work).

The solution is to change the permalink structure in WordPress.
