Laravel 5.3 Forgot Password raises InvalidArgumentException

I'm using Laravel 5.3 Authentication and when I use Forgot Passsword link, I get an error.

InvalidArgumentException in FileViewFinder.php line 112: No hint path defined for [notifications].

I have tried following options suggested by other posts in Stackoverflow.com.

1. Modify the name of config.php project/bootstrap/cache/config.php to another name like config.php.old
2. php artisan config:cache to clean up the cache.
