There is a very simple article titled "How do I change the 'Sales Message Goes Here' or 'Tagline Here' text?"

I've re-read the article numerous times and repeatedly started over from scratch. I expect it to work smoothly, but it doesn't. The "classic" version of header.php is loading. When I change name of "classic" to "classicX", the application loads values from the "core" version, ignoring "custom" version.

I am running v. 1.3.6 and my host is Crystal Tech. This is my first attempt at customization, so I could be missing something.

Thank you for any help.
