I just ran a composer update and now when I try to access my website I get this error:
ClassNotFoundException in SecurityController.php line 28: Attempted to load class "AbstractController" from namespace "Symfony\Bundle\FrameworkBundle\Controller". Did you forget a "use" statement for another namespace?
When I go into vendor/friendsofsymfony/user-bundle/Controller/SecurityController.php even PHPStorm is now telling me "Undefined class AbstractController"...
What happened to "AbstractController" and how do I get my application to work again? I've searched online and found one person who had the same issue, but there's not fix. https://github.com/FriendsOfSymfony/FOSUserBundle/issues/2678
