Unable to display Flash messages in Cakephp 3.x -

-

i not able flash messages display on of views.

an example of trying call flash message in controller (which untouched cake bake except message, syntax has stayed same).

$this->flash->success('your account has been created!');

in appcontroller initialize function:

$this->loadcomponent('flash');

in default layout:

<?= $this->flash->render() ?> <?= $this->fetch('content') ?>

i not getting error messages, far can see , after doing lots of research issue seems set correctly.

the flash messages visible in session, when declare them key:

$this->flash->default('a message... ',['key' => 'cutom_error_key',]); $this->flash->success('welcome',['key' => 'loggedin']);

i have made sure valid flash .ctp files in element\flash folder (copied working project after running issue).

any ideas causing issue?

add following in controller:

use cake\controller\component\flashcomponent;
