wp-login.php postpass no redirect

[lukelr]

I'm running wordpress 4.9.8 on an Archlinux host. Whenever I try to password protect a post, the redirection after entering the correct password fails. Going back to the post using the browser history works, and the post is unlocked, but only a blank page is visible to the user after entering the password.

I suspect

wp_get_referer();

to be the root of the problem. I've added some debug output to the code:

$referer = wp_get_referer();
if ( $referer ) {
	$secure = ( 'https' === parse_url( $referer, PHP_URL_SCHEME ) );
	print "True";
} else {
	$secure = false;
	print "False";
}

and it prints "False" on that formerly blank white page after entering the password. Also adding

print $referer;
print $_SERVER['HTTP_REFERER'];

to the code prints nothing.

I've tested different up-to-date browsers: Firefox, Chromium on Linux, Firefox, Opera on Windows 8.1, Firefox Klar, Safari on iOS, to no avail. Only Internet Explorer on Windows 8.1 works as expected, the redirect occurs immediately.

Any ideas what could cause this problem, or how to further debug this?
