Problem with registration form

Hi, I’m creating a new project with version 2025.2 and I have a strange problem with the registration form: it doesn’t allow me to register producing the error - the authenticator does not support the request. {“firewall_name”:“main”,“authenticator”:“Symfony\Component\Security\Http\Authenticator\FormLoginAuthenticator”} -
I downloaded the demo2025 file and installed it locally and even with this project I get the same error.
The login works regularly.
Any suggestions?

Are you using a custom template for the registration page? Make sure you post back to the registration page.

I use the standard template proposed by phpmaker.
I do not use custom templates for the login form.
The same problem occurs with demo2025

If you use Modal registration page, try uncheck it and test again.

I unchecked the use Modal. But it still doesn’t work. debug returns the error, the user is not registered in the DB and the registration form remains without reporting any error on the web page. I even tried to change server, but same thing. I converted a simple project of two tables one of which the users 2024 table in 2025 and in the 2025 version it doesn’t work while it works correctly in 2024. I don’t use any custom form and I don’t use scripts or other code.
