Answer 1

i have following yii2-cms and it's work great
set instance error occur due to they can not find out given class and that's possible due to miss configuration.
follow Configuration Link https://github.com/yii2mod/yii2-cms#configuration
1) To use this extension first you need to configure the comments extension, after that you have to configure the main config in your application:
'modules' => [
'admin' => [
'controllerMap' => [
'cms' => 'yii2mod\cms\controllers\CmsController'
// You can set your template files
// 'layout' => '#app/modules/backend/views/layouts/main',
// 'viewPath' => '#app/modules/backend/views/cms/',
],
],
],
You can then access to management section through the following URL:
http://localhost/path/to/index.php?r=admin/cms/index
2) Add new Rule class to the urlManager array in your application configuration by the following code:
'components' => [
'urlManager' => [
'rules' => [
['class' => 'yii2mod\cms\components\PageUrlRule'],
]
],
],
3) Add to SiteController (or configure via $route param in urlManager):
/**
* #return array
*/
public function actions()
{
return [
'page' => [
'class' => 'yii2mod\cms\actions\PageAction',
// You can set your template files
'view' => '#app/views/site/page'
],
];
}
And now you can create your own pages via the admin panel, and access them via the url of each page.

Answer 2

Yes error is solved by following proper Configuration STEP.
Error is occur due to miss configure second step
2) Add new Rule class to the urlManager array in your application configuration by the following code:
'components' => [
'urlManager' => [
'rules' => [
['class' => 'yii2mod\cms\components\PageUrlRule'],
]
],
],
Full Configuration you need to did :
1) To use this extension first you need to configure the comments extension, after that you have to configure the main config in your application:
'modules' => [
'admin' => [
'controllerMap' => [
'cms' => 'yii2mod\cms\controllers\CmsController'
// You can set your template files
// 'layout' => '#app/modules/backend/views/layouts/main',
// 'viewPath' => '#app/modules/backend/views/cms/',
],
],
],
You can then access to management section through the following URL:
http://localhost/path/to/index.php?r=admin/cms/index
2) Add new Rule class to the urlManager array in your application configuration by the following code:
'components' => [
'urlManager' => [
'rules' => [
['class' => 'yii2mod\cms\components\PageUrlRule'],
]
],
],
3) Add to SiteController (or configure via $route param in urlManager):
/**
* #return array
*/
public function actions()
{
return [
'page' => [
'class' => 'yii2mod\cms\actions\PageAction',
// You can set your template files
'view' => '#app/views/site/page'
],
];
}
And now you can create your own pages via the admin panel, and access them via the url of each page.

Answer 3

You seem to be using the cms extension in your site component as-is.
In your web.php file, add this:
'components' => [
...
'i18n' => [
'translations' => [
'*' => [
'class' => 'yii\i18n\PhpMessageSource',
'basePath' => '#app/messages'
'sourceLanguage' => 'en',
],
],
],
]
...,
'controllerMap': => [
'cms' => 'yii2mod\cms\controllers\CmsController'
],
NOTE: You should exclude the path about configuring it as a component in the admin module since you're not using it anyway.
If you were using it in a module, then the steps documented in the README is just fine for you.
