Symfony 3.0.1 CSRF token present but invalid

Question

I am having this strange issue with a fresh Symfony 3.0.1 installation. I generated a new CRUD Controller with a Form PostType which contains an url and a title. Nothing fancy.<

Answer 1

It seems to be a bug in symfony version >3.0, <3.0.3.

As @yellowmen pointed out, changing the framework.session.save_path in the config.yml fixes the problem.
