Why can't register when creating a new yii2 project?

Question

Yii

I have this problem: I
installed yii2, I open it in the browser, after filling out the registration form, the data goes to the database,



but an error pops up in the browser.



Apparently, the server complains, but what exactly is wrong with it in my case, how to understand?
I use openserver, the settings are php 7.1-x64, apache-php-7-x64, mysql-5.6

Answer 1

for starters, it would be worth deploying the application in the dev environment, not prod.
But if so, then in index.php you need to change

defined('YII_DEBUG') or define('YII_DEBUG', false);
defined('YII_ENV') or define('YII_ENV', 'prod');

on the

defined('YII_DEBUG') or define('YII_DEBUG', true);
defined('YII_ENV') or define('YII_ENV', 'dev');

And then see what exactly is wrong.

Answer 2

The problem was solved by adding 'useFileTransport' => trueto the file common/config/main-local.php
After that, mailer will add letters toruntime/mail
