this is my ..app/config/security.yml

security:

# https://symfony.com/doc/current/security.html#b-configuring-how-users-are-loaded

security: encoders: FOS\UserBundle\Model\UserInterface: bcrypt

   role_hierarchy:
       ROLE_ADMIN:       ROLE_USER
       ROLE_SUPER_ADMIN: ROLE_ADMIN

   providers:
       fos_userbundle:
           id: fos_user.user_provider.username

   firewalls:
       main:
           pattern: ^/
           form_login:
               provider: fos_userbundle
               csrf_provider: security.csrf.token_manager # Use form.csrf_provider instead for Symfony <2.4
           logout:       true
           anonymous:    true

   access_control:
       - { path: ^/login$, role: IS_AUTHENTICATED_ANONYMOUSLY }
       - { path: ^/register, role: IS_AUTHENTICATED_ANONYMOUSLY }
       - { path: ^/resetting, role: IS_AUTHENTICATED_ANONYMOUSLY }
       - { path: ^/admin/, role: ROLE_ADMIN }

    main:
        anonymous: ~
        # activate different ways to authenticate

        # https://symfony.com/doc/current/security.html#a-configuring-how-your-users-will-authenticate
        #http_basic: ~

        # https://symfony.com/doc/current/security/form_login_setup.html
        #form_login: ~

please help me thanks :)

if this is a direct copy paste of your security.yml file, then role_hierarchy, providers, firewalls, access_control, main, seem to be only 3 spaces indented instead of 4. — Andrew Nolan

This is really tough to notice, but...

There is an extra space before the main: that appears after the access_control: block. Remove the space and you should be good to go.

I found this by copying your file into Netbeans IDE. It's pretty good at identifying YAML file errors.

Good luck.

Same error message? If you continue to get YAML parse errors try creating your project in Netbeans and use it to view your YAML files. Symfony YAML files are quite strict about spaces and such.
