My login form only reloads the page but doesn't log the user in

My login form is broken after I took out the "email" and "name" from the form, took out "email" and "name" from protected fillable in User.php. I also made the redundant fields nullable in the database. The user should be able to login using their "username" and "password". The registration form works fine, its just the login form that is causing issue.
