j'y connais rien en symphony ni en yaml, mais selon ta doc il ne faut pas de "true" après form_login:

bonjour j'essaye activement de changer le check_path comme indiqué sur la doc

[code]security:
# https://symfony.com/doc/current/security.html#where-do-users-come-from-user-providers
providers:
from_database:
entity:
class: App\Entity\User
property: username
firewalls:
dev:
pattern: ^/(_(profiler|wdt)|css|images|js)/
security: false
main:
anonymous: true

# http_basic: true
# https://symfony.com/doc/current/security.html#firewalls-authentication

# https://symfony.com/doc/current/security/impersonating_user.html
# switch_user: true

form_login: true
check_path: login


# Easy way to control access for large sections of your site
# Note: Only the *first* access control that matches will be used
access_control:
- { path: ^/admin, roles: ROLE_ADMIN }
# - { path: ^/profile, roles: ROLE_USER }
#encoders:

[/code]

la syntaxe est bonne si j'en crois https://symfony.com/doc/current/security/form_login.html

Mais symfony me renvoie une erreur :

The file "/var/www/html/my_project_name/config/packages/security.yaml" does not contain valid YAML: A colon cannot be used in an unquoted mapping value at line 23 (near " ") in /var/www/html/my_project_name/config/packages/security.yaml (which is loaded in resource "/var/www/html/my_project_name/config/packages/security.yaml").

merci pour le temps que vous voudrez m'accorder !
