Checkout settings are ignored I have configurations on store>configuration>completion messages. But they are not reflecting on the site. For example I have set the checkout page as a node I created but it's still using the default checkout page. I have cleared all the cache. What am I missing?
AFAIK the checkout page is dynamically generated by Ubercart, you cannot create a node for it. You can theme the dynamically generated page or alter it through custom modules if needed, see several very helpful Ubercart tutorials here: https://drupal.org/project/ubercart
