deploy symfony 3 on ubuntu
<p>I try to run a project with symfony 3 on ubuntu (Ubuntu 14.04LTS, Apache 2.4.7 , MYSQL 5.5.49, php 5.5.9-1ubuntu4.16). But I have this error when I run the web/app_dev.phpUnable to find template</p>

<pre><code>Unable to find template "PolarBundle:Default:index.html.twig" (looked into: /var/www/html/polarUTC/vendor/symfony/symfony/src/Symfony/Bridge/Twig/Resources/views/Form, /var/www/html/polarUTC/vendor/knplabs/knp-menu/src/Knp/Menu/Resources/views).
500 Internal Server Error - InvalidArgumentException

</code></pre>

<p>I try to run in WAMP and MAMP and I don't have problem. 
I check the web/config.php and I have no error.</p>

<p>Thank you for your help</p>

<p>Bye,</p>
