I'm sorry if this is in the wrong place.
Using the Black Letterhead, I've modified the CSS. The only problem is that when people comment, they have to push the back button 3 times in order to get back to the main blog page.
I've checked through forums and saw that the way to get a clickable header is to modify the PHP.
I don't see a PHP modification option in my admin panel.
Can someone direct me to where I need to go to update the PHP in order to make my header clickable?
