Clear your browser's cache.

We made a change in restore.php and made the respective change in our JavaScript. However, your browsers seems to have cached the older version of the JavaScript which expected a different format of the data returned by restore.php. Clearing the browser's cache will solve that problem.

This may not work if you are restoring a backup taken with an older version of Akeeba Backup. In this case the restore.php file will be replaced during the restoration so the next request to it will fail because the old version of restore.php responds. In this case just use Kickstart to extract your backup archive.
