body: <p>I have this return symfony error with all my url website : <br>
  "<strong>ClassNotFoundException: Attempted to load class "DoctrineFixturesBundle" from namespace "Doctrine\Bundle\FixturesBundle" in C:\dev\Apache2.4.6\htdocs\MySite\app\AppKernel.php line 23. Do you need to "use" it from another namespace?</strong>" <br></p>
  
  <p>This error appear when I modified the config.yml (part doctrine orm)for resolve others problem but it's not resolving. Indeed a back my change in this file and re-run my website but now nothing run correctly. I have this error anytime and anywhere.</p>
  
  <p>I copy my code here but for response at simple question :<br>
  - <em>do you have adding this line in AppKernel.php</em> : $bundles[] = new Doctrine\Bundle\FixturesBundle\DoctrineFixturesBundle(); ? <strong>RESPONSE : YES</strong> <br>
  - <em>do you have install fixtures bundle ?</em> <strong>RESPONSE : YES</strong> <br>
  - <em>do you have install/update and self-update composer ?</em>  <strong>RESPONSE : YES</strong> <br>
  - <em>do you have load fixtures in DB ?</em> <strong>RESPONSE : YES (it run perfectly)</strong> <br>
  - <em>do you have cleaning the cache ?</em> <strong>RESPONSE : YES</strong></p>
  
  <p>All my fixtures engine run correctly just before this generate error.</p>
  
  <p>AppKernel.php</p>
