Error when trying to reset password

I noticed that when a member tries to reset their password and they go to the reset url (that gets emailed to them) then they just see an error page that says this:

Catchable fatal error: Object of class WP_Error could not be converted to string.

It says its in this file: class-ms-view-shortcode-login.php on line 510

Why is this happening? Or is this issue fixed with the most recent update?
