To fix this, do the following:

  • create the default image folder for your CMS platform on the target site:

        Joomla – /images/
WordPress – /wp-content/uploads/
Drupal – sites/default/files

  • Set the numeric value to be ‘777’, then tick to ‘Recurse into subdirectories’ and ‘Apply to all files and directories’, making it writable.
  • folder-permission

  • After that, start the migration wizard from the beginning.
