cannot locate child theme

Hi

I have read the documentation about child themes and uploaded the plugin “child themify” and followed the steps. However, when I get to the last step

goto appearance > themes > find your child theme…I can’t find it!?! The previous screen said that I had successfully created it but I am unable to locate it even with after searching under themes.

I have searched https://www.cara-lea-dance.co.uk/wp-admin/themes.php
and still cannot see where to start adding my code.

Any ideas?

Thanks in advance, I appreciate your help!
