I just installed FEC but I'm finding that the login page has not changed. After clicking the "go to checkout" button I'm still directed to the standard Zen Cart login page with "Welcome, Please Sign In" at the top.

I followed the instructions completely, and after following them I went to the Fast and Easy Checkout Configuration menu in the Zen Cart admin and changed the One Page Checkout option to true. Is there anything else I need to do to activate the mod?

Sorry, I know this seems like a bone-headed issue, but I'm stumped. I'm a professional web developer so I'm pretty sure I executed the install correctly.
