Setup The Checkout Url
Setup the checkout URL of your online store by click on the ‘Store Setup’ tab and then the ‘Checkout URL, SSL Settings and Payment Provider Selection’ link.
The Checkout URL controls where the Site Store Pro application will look for the “Checkout” and “My Account” areas on your Site Store Pro enabled online store.
When the website is “live”, the Checkout URL field should contain your secure domain URL (i.e. https)
When setting up your initial Site Store Pro installation, you may not have an SSL certificate available and/or may have installed the files into a subdirectory for testing. In these situations, simply enter the same URL that was entered as the Store (Website) URL. The Checkout URL can be changed when you receive your SSL certificate.
