session_cache_limiter error in symfony2.8 with php 7.2

Question

I am working on the project which is already build on Symfony. The versions and server details are as below

PHP: 7.2

Webserver: apache 2.4.6

Symfony: 2.8.1.1

I am getting below warning while initializing new session on my controller. This issue comes only when I am working on debugger mode(app_dev.php) not on production environment.

"Warning: session_cache_limiter(): Cannot change cache limiter when session is active"

I have gone through the issue over google and seen that it is core PHP warning.

How can we solve this with symfony 2.8 version?

Answer 1

It seems somewhere in the framework session_cache_limiter() is called after session_start(). It should be called before.
