I'm using a theme found in the library called "Pink Gooberhead". It includes a nav/link bar horizontally across the top. (See http://www.MelsBGC.com)

By default, the links are "Home", "View Account", "Downloads", and "Forums". I opened the "theme.html" file from inside the theme and changed these links (both link text and destination URL) but it simply does not take. It's odd... The current theme.html file is here: http://www.melsbgc.com/themes/PinkGooberhead/theme.html

Can someone take a look and see if they see where my problem is? You'll see clearly that in this file I've changed the links to "Home", "My Account Info", "Mantourage.com", "Forums".

I'm guessing that this isn't the proper file to be editing for this, but... well, I'm lost. Any help?

This is because of the cache feature that your changes don't show up. You can login to your administration panel and go to system > preferences > general settings.

Check to yes this option: Check templates for modifications ?

When you've finished doing changes to the theme check it back to no.

This will refresh the template cache stored in templates_c folder.
