Remove comment url field

Hey guys I’m trying to remove the URL field from the comment form using some code I found here in the forum but it doesn’t seem to be working anymore.

Here’s the code:

function remove_comment_fields( $fields ) {
	unset( $fields['url'] );

	return $fields;
}

add_filter( 'comment_form_default_fields', 'remove_comment_fields', 60 );

And here’s the original thread:

I’ve tried a bunch of different priority levels with no luck. Any ideas? Thanks!
