What happens to child theme if I change to new version of parent theme?

If you want to be super safe, you can do this method:

  • I would recommend first connecting to the theme folder via FTP. If
    you haven’t made any templates or custom php pages etc, you can
    rename the theme folder _backup at the end.
  • Then just drag in the new theme in the same theme folder location.
  • Simply go to your dashboard and activate the new theme.
  • Then activate the child theme again and see if there are any issues.

If the new theme messes up your child theme, you can try to resolve the issues, or revert back to the old version by deleting the new theme, removing the _backup on the old theme folder and reactivating everything.

Hope this helps!
