I'm Lizzy, one of the Gurus on the support team at Shopify. Thank you for sharing your question with us in the community forums!
I took a quick peek at your store, and noticed that your password page is still enabled. Am I correct in assuming that your store is on a trial, and that you haven't yet selected a plan? If that's the case, then your checkout won't be accessible, even in test mode. Before you choose a plan the checkout is completely locked.
Not to worry though! You can choose a plan, from the options here, and you won't be charged until your trial is over. That way you can unlock all of the features that you'll need right away. You can also keep your password page enabled for as long as you need, so you can keep testing!
Have you had a chance to think about which of our plans would be the best fit for your business? Don't hesitate to let me know if you have any questions about the features!
