black page = errors. There’s an error in your functions.php somewhere, I’d say.

If you;re making a *child* theme, and you place a copy of the original theme’s functions’ file in your child theme, it WILL white-out your site. Because the child is *already* pulling the functions file.

putting it in there is like putting it in there twice. hence the error. If you find your server error logs, I’m sure they’ll say “can’t redeclare and other duplicate function notices.
