You will need to make some changes in Ecwig before the Ecwid Checkout will work on your website. In particular, you need to edit the 'Instant Site address'.

To edit your Ecwid Instant Site address visit: https://my.ecwid.com/ login and in the panel on the left click on Website. Then click the Edit button.

Click on the Address Settings box.

In the input box for the free *********.ecwid.com subdomain enter your new subdomain name.

For our ip-approval.com domain we would use ip-approval-com and our free ecwid subdomain would become ip-approval-com.ecwid.com

In other words, replace the dots in your domain or subdomain with a dash.

Click Save when finished.
