UrlManager stopped working in Yii2. Where to look for an error?
The debugger gives:
exception 'yii\base\InvalidRouteException' with message 'Unable to resolve the request "login".' in Z:\home\yii.one\www\vendor\yiisoft\yii2\base\Module.php:462 Stack trace: #0 Z:\home\yii.one\www\vendor\yiisoft\yii2\web\Application .php(100): yii\base\Module->runAction('login', Array) #1 Z:\home\yii.one\www\vendor\yiisoft\yii2\base\Application.php(375): yii \web\Application->handleRequest(Object(yii\web\Request)) #2 Z:\home\yii.one\www\index.php(12): yii\base\Application->run() #3 { main} Next exception 'yii\web\NotFoundHttpException' with message 'Page not found.' in Z:\home\yii.one\www\vendor\yiisoft\yii2\web\Application.php:112 Stack trace: #0 Z:\home\yii.one\www\vendor\yiisoft\yii2\base\Application .php(375): yii\web\Application->handleRequest(Object(yii\web\Request)) #1 Z:

In web/.htaccess

RewriteEngine on

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

RewriteRule . index.php

To the root of the site .htaccess

<IfModule mod_rewrite.c>
  Options +FollowSymlinks
  RewriteEngine on
</IfModule>

<IfModule mod_rewrite.c>
   RewriteCond %{REQUEST_URI} ^/.*
   RewriteRule ^(.*)$ web/$1 [L]

   RewriteCond %{REQUEST_URI} !^/web/
   RewriteCond %{REQUEST_FILENAME} !-f [OR]
   RewriteCond %{REQUEST_FILENAME} !-d
   RewriteRule ^.*$ web/index.php

</IfModule>

In urlManager

UrlManager:
'urlManager' => [
'enablePrettyUrl' => true,
'showScriptName' => false,
'rules' => [
'' => 'site/index',
],

The site should open at site.com (main page), web is removed from the address.
If the action is in the SiteController controller, then add
the login form to the urlManager at site.com/login
You may also need to specify 'loginUrl' in the configuration
Example (specify your own data and paths)

'user' => [
            //'identityClass' => 'app\modules\users\models\Users',
            'identityClass' => app\modules\users\models\Users::className(),
            'enableAutoLogin' => true,
            'loginUrl' => ['users/default/login']
        ],

Issue resolved. I screwed up with the config/web. Updated - everything worked...
