Before cloning your webpages you'll need to create a server.
1. Go to Website > Servers and press New Server button
2. Choose region where your server will be created. We recommend choosing a region as close geographically as possible to your audience. Then press Create Server button.
3. After doing this your server will be initialized for about 3-5 minutes. Press Refresh button a couple of times before you see "ok" in status column. After that you are ready to add domains for cloning websites.
