For some reason my checkout page is bugged, and I didn't change anything as far as I know. Usually the flow goes like this:

Add product > Go to cart > Go to checkout > Fill out details OR login > 'Place order'.

If I log in at that detail page, I get to select my address from my account, which is good. And then I can continue. However, if I'm on a random page and login from there, and then go to my cart, I run into an issue. When I go to the next page (checkout), it remains blank. I only see the summary of items on the right side, but not the 'Place order' button, nor my address(es).

Also, this 'one page refreshing' thing bugs me. When I have my email auto-filled in at the checkout page, I have to add and remove a character to have the javascript triggered to show the password field. Can't I just add a page in between this process giving people the option to choose 'login', 'register', or 'guest checkout'.

Hope someone can answer these questions.
