PHP Error on Password Reset

I’m seeing a PHP error when trying to reset my password: Fatal error: Call to undefined method stdClass::get() in /home/cycle890/public_html/[domain]/wp-content/plugins/better-wp-security/modules/free/strong-passwords/class-itsec-strong-passwords.php on line 68

No idea what version, as I cannot log in.
