title: Woocommerce can't disable Guest Checkout
body: <p>I am using Woocommerce and am having problems disabling the guest checkout.</p>
  
  <p>I have made sure <strong>'Enable Guest Checkout'</strong> is <strong>unticked</strong> in the settings page but people are still able to checkout without creating an account or logging in.</p>
  
  <p>Is there somewhere else I should be setting this?</p>
