Symfony app on subdomain error 500
<p>I created website based on Symfony3 which is running fine on localhost. Now the project is finnished and needs to be deployed on production server's subdomain and I get the 500 error when I try to access it. No URL works, even web/config.php shows error 500.</p>

<p>The project is located on subdomain like this: www.subdomain.domain.cz/web</p>

<p>Do I need to configure something to be able to run project on subdomain? I don't have access to apache. </p>

<p>i tried to create simple php file with echo("hello world"); located in subdomain's root and it worked fine.</p>

<p>I cleared the cache before deploying.</p>
