Bug: 404 Errors

Created by: michaelspellacy

Ran a link scan on your site and noted that humans.txt is throwing a lot of 404's when you have pages loading from within a sub-directory. Adding a forward slash should globally clear that one right up.

Before: <link rel="author" href="humans.txt">

After: <link rel="author" href="/humans.txt">

Also spotted a few other 404's:
