Login Issue

Hello.
Just updated from 4.0.8 to 4.0.12 … on two site:
same issue: blank page on http://www.url.ext/myloginslug … for now i fixed disabling hide login area ( so i can access ).
To do this : rename plugin directory ( with filezilla ).. ( so wp deactivate it ) and login to yoursite.etx/wp-admin.
Rename back the plugin dir ( with filezilla ), enable it, go to setting and deactivate hide login area.
I’m waiting on a fix
