Symfony 2 InvalidArgumentException：文件app / config / config_prod.yml不存在

Question

I'm trying to access a Symfony Installation on my VPS running CentOS.

The files /app/config/config_dev.yml and /app/config/config_prod_yml exist on the server. I even chmodded them to 0777 for testing purposes but I still get the error that they don't exists.

Full trace:

InvalidArgumentException: The file "/home/XXXXX/public_html/app/config/config_dev.yml" does not exist.

Answer 1

It was a CHMOD issue where PHP didn't have access to the symfony core files.
