There could be some causes:
1. Make sure you have already updated nameservers.
If you are using your own domain (like yourdomain.com, for example), you need to point your domain to our nameservers to get it working. You can find the nameserver details after logging on to your Customer Area. You have to wait 24-48 hours after the nameservers are updated before your domain starts working.
2. Make sure you have a public_html folder created.
If your site is missing the public_html folder, you will not be able to use website builder.
3. Use Internet Explorer, Firefox or Opera browsers..
Our website builder has support for these browsers only. We do not guarantee that the builder will work with other browsers.
