Can't access to back office

[Nandos]

On my test server, when I try to access to my backoffice, I get this error (dev mode already enabled):

 

 

Fatal error: Call to a member function getContainer() on null in /.../prestatest/classes/Link.php on line 696

 

There I found this code:

$pagePreference = $kernel->getContainer()->get('prestashop.core.admin.page_preference_interface');

Any guess on what it could be? I'm trying to figure out this since this morning, but I didn't found any solution so far.
