At times UltraCart will need to make changes, updates or general fixes to existing Themes. Once that occurs, you'll see a NOTE posted on your theme icon indicating the Theme number.
At StoreFronts click on Themes under the Appearance tab.
Note: Although your Theme can also be Upgraded at the General Tab, upgrading should be accomplished at the Themes tab. There, you have the opportunity to duplicate, which is highly recommended prior to upgrading.
It's always wise to duplicate (copy) your Theme prior to upgrading. That way you can always go back to the original. The following is a link to How to duplicate your Theme.
TODO: Need to show the dialog that appears if there is a conflict. Then, provide a link to the topic for dealing with conflicts.
