Session start error

[garybarnes995]

Hi,

I've just installed everything, generated the admin pages and the list pages display perfectly. When I click to EDIT, I get the error listed below. Any ideas why this should be, and why the first page should work and not the EDIT page?

RuntimeException in NativeSessionStorage.php line 131: Failed to start the session: already started by PHP.

Hi !
I've found a solution that works for me !
Edit the file\vendor\symfony\security-csrf\TokenStorage\SessionTokenStorage.php
Replace every
if (!$this->session->isStarted())
by
if (!$this->session->isStarted() && session_status() === PHP_SESSION_NONE )
