Yii: Same route but only GET works after confirming there's no controller filter - yii

Question

My urlManager rules: (basically the one comes default)
'<controller:\w+>/<id:\d+>'=>'<controller>/view',
'<controller:\w+>/<action:\w+>/<id:\d+>'=>'<controller>/<action>',
'<controller:\w+>/<action:\w+>'=>'<controller>/<action>',`
My controller:
class SiteController extends Controller {
public function actionSubscribe() {
echo 'gdg';
die();
}
}
My view:
<form method="POST" action="<?php echo $this->createUrl('site/subscribe'); ?>" style="display: inline;">
<input style="margin: 0 18px 0 6px;" type="text" value="e-mail"/>
</form>
When I access it using the url http://localhost/site/subscribe directly it works, but when I type something in the text field and push my enter button to post the form it says The system is unable to find the requested action "error".
I'm very certain that it has something to do with my form. I have so far no problem using active form but for this form I don't have a model and I don't want to use form builder. Any help?

"When I access it using the url http://*/site/subscribe directly it works"
=> You execute subscribe action with GET method.
"but when I type something in the text field and push my enter button to post the form it says The system is unable to find the requested action "error"."
=> You execute subscribe action with POST method.
=> There are some errors and I think Yii try to handle error with your default configure:
return array(
......
'components'=>array(
'errorHandler'=>array(
'errorAction'=>'site/error',
),
),
);
However, Yii can't find error action with your SiteController so it throws The system is unable to find the requested action "error". You can add error action to see information about errors like:
public function actionError()
{
if($error=Yii::app()->errorHandler->error){
$this->render('error', $error);
}
}
More info: The above error variable is an array with the following fields:
code: the HTTP status code (e.g. 403, 500);
type: the error type (e.g. CHttpException, PHP Error);
message: the error message;
file: the name of the PHP script file where the error occurs;
line: the line number of the code where the error occurs;
trace: the call stack of the error;
source: the context source code where the error occurs.
