Dashboard disappears when child theme functions.php file is uploaded

I have a simple functions.php file in my child theme, just to add two sidebars. However, when it is on the server, I cannot login to my dashboard. WordPress just takes me to a blank page. As soon as I delete the file and hit refresh, it loads just fine. The same happens on logout.

I’m not sure what’s going on. My functions.php file is very simple:

<?php

register_sidebar( array(
		'name' => 'Home Sidebar',
		'id' => 'sidebar-home',
		'before_widget' => '<aside id="%1$s" class="widget %2$s">',
		'after_widget' => "</aside>",
		'before_title' => '<h3 class="widget-title">',
		'after_title' => '</h3>',
	) ); 

register_sidebar( array(
	'name' => 'Archives Sidebar',
	'id' => 'sidebar-archives',
	'before_widget' => '',
	'after_widget' => '',
	'before_title' => '',
	'after_title' => '',
	) ); 

?>

Thanks in advance.
