When I try to log in as a subscriber to my boards, I get this error:

ArgumentCountError thrown

Too few arguments to function Automattic\Jetpack\Sync\Modules\Users::wp_login_handler(), 1 passed in /home/s551757/public_html/hp_wordpress/wp-includes/class-wp-hook.php on line 286 and exactly 2 expected

Then, when I refresh the page, I can view the boards, but I am also viewing the site editor. Help!
