SessionHandler::write(): Parent session handler is not open

Question

I'm using FOSFacebookBundle in Symfony 2.3 as it says in the Integration with FOSUserBundle documentation. And edited security.yml, ran the code but I got the error:

Warning: SessionHandler::write(): Parent session handler is not open in /var/www/my/app/cache/dev/classes.php line 407

so I gave the permissions:

sudo chmod 777 -R app/cache
sudo chmod 777 -R app/logs

When I login again, and then logout page I get the same error.

I see this https://github.com/symfony/symfony/issues/5868 and update the php.

But this problem is not solve I don't know why ? Any one know please tell me ?

Answer 1

The problem like mentionned in the ticket on github is a bug related to PHP so there is noting to do in the Symfony2 side.

Consider moving away from your current php 5.4.x to a newer version.

According to this comming you should be at least using >= php 5.4.11

Fast solution could be:

logout:
    invalidate_session: false

EDIT:

Be aware session will not be destroyed after logout. I would recommend @Tristan solution.
