I have a site at http://www.threeforksbible.org
in WP 3.5.2. The client would like to change the Sermons page in the main body to be titled "Messages" instead of "Archives" (although the sidebar Archives header is fine). I have searched through the theme editor files and through the css files without success to find and rename the header. I expect it to be editable in a css or php file, but which one?
