I have the white screen of death whenever logging in, updating a post, or saving an edit. I've narrowed down the source of the problem to this code (it's not long):
However, I've no idea what may be wrong with the code (I'm a WP noob).
Any help would be greatly appreciated.
P.s. I'm using a child theme and that will be the only code in the function.php file (along with a bit lowering header size).
