Hey!
Where does it say it already has pages made? I’ve not seen that message before. Have you imported demo content via theme options > general tab?
If its a fresh install, you can use the WP RESET plugin to clear out all the data, then you can import demo content again.
If the issue persists, please post this up on our support forum and our support team will take good care of you. Create a new topic with details about the issue, your site URL and version of Avada. For faster service, please include your WP and FTP login info when creating the thread.
