When making changes in header.php, they're showing up on the index, but not any of the other pages, like a single post. I know that at one time they did, because my single post pages header matches the index.
I even added some code into footer.php, and it showed up on the index, but not the individual posts.

Am I just overlooking something simple (I hope)? Any ideas or direction would be appreciated.
