Help: Cannot create references to/from string offsets in wp-includes/user.php

Hi all,
after a redux framework plugin update my website is down (frontend + backend).
I tried to deactivate all plugins whitout resolve.
I activated debug and I found this:

Fatal error: Uncaught Error: Cannot create references to/from string offsets in /home4/bmwmotoclub/public_html/wp-includes/user.php on line 54
( ! ) Error: Cannot create references to/from string offsets in /home4/bmwmotoclub/public_html/wp-includes/user.php on line 54

->
do_action_ref_array( 'wp_authenticate', array( &$credentials['user_login'], &$credentials['user_password'] ) );

	if ( '' === $secure_cookie )
		$secure_cookie = is_ssl();

Anyone can help me, I can’t do login.

Thanks
