To correct this, you’ll just need to update the Store URL in your 3dcart settings.
You may do this by using the following steps. From your Online Store Manager go to:
- Settings =>General =>Store Settings
- Click on the “Store” tab along the top of the section
- Change the “Store URL” to reflect your store url ie. http://www.yourwebsite.com
Once this is done, http://www.yourwebsite.com/sitemap.xml will show the correct addresses for the URLs.
