PHP Code:
if (THIS_SCRIPT == 'About Us')
Is there a line like this at the top of your about us page:
PHP Code:
define('THIS_SCRIPT', 'xxxxx');
The xxxxx is what you put for 'About Us' as that is what THIS-SCRIPT is defined as. You will need to look in your page to find that, and if it isn't there, then enter it yourself and define it with a unique name.
HTML Code:
{vb:rawphrase roaringseason_about}
Did you create a phrase called "roaringseason_about" and enter the text for your tab name?
