What I wanted to mention was the main template that ships with PS3 - it calls the admin.css file for some reason. It screws up the pages you create with the main template. Just fYI.
Edit: It also has home.css in the head portion as well. I don't understand why. But once you remove those two lines, it's back to normal (similar to the pre-made pages, like tos, and privacy, etc)
Can you elaborate on this a wee bit? You're referring to Main.dwt.php right?
How does it screw up the pages? I'm asking because I'm having problems getting my modifications to stick.
