Yii Property “Cwebuser.bootstrap” Is Not Defined

I have a site using the yii framework. As the first thing, after i got the site up and running, I wanted to install bootstrap (yii-bootstrap-2.1.0.r355.zip). This, however, did not go very smooth.

I get the following error "Property "CWebUser.bootstrap" is not defined."

The Bootstrap extension is placed as /blog/protected/extensions/bootstrap

My main config file looks like this


<?php


// uncomment the following to define a path alias

// Yii::setPathOfAlias('local','path/to/local-folder');


// This is the main Web application configuration. Any writable

// CWebApplication properties can be configured here.


	Yii::setPathOfAlias('bootstrap', dirname(__FILE__).'/../extensions/bootstrap');
