After click on sign up button

Hi All,

I am newbie for the yii2. I need a big help from all of you.

I have the signup page, once click on submit i get the error as below,

Below are the code for the common >> config >> main-local.php

‘mailer’ => [
‘class’ => ‘yii\swiftmailer\Mailer’,
‘viewPath’ => ‘@common/mail’,
// send all mails to a file by default. You have to set
// ‘useFileTransport’ to false and configure a transport
// for the mailer to send real emails.
‘useFileTransport’ => false,
‘transport’ => [
‘class’ => ‘Swift_SmtpTransport’,
‘host’ => ‘’,
‘username’ => ‘9b3af242d96af3’,
‘password’ => ‘8396741fae50bb’,
‘port’ => ‘2525’,
‘encryption’ => ‘tls’,

Appreciate for the advise & solution.

Many Thanks.

Now i get this error

Message is clear, you didn’t put a sender e-mail, which is required.
