Hi, I'm running PHP 5.4.3-1 at Fedora 16 32bits so I try with Symfony 2.0.14 and Symfony 2.0.13, in both cases the .tgz file, uncompress in my ROOT_DIRECTORY at /var/www/html/symfony, set owner to apache:apache recursive for all the directory and set app/cache and app/logs permission to 777 recursively too, and both cases return the same error/issue:

Whoops, looks like something went wrong.

1/1InvalidArgumentException: There is no extension able to load the configuration for "framework" (in /var/www/html/symfony/app/config/config_dev.yml). Looked for namespace "framework", found none

Any advice on this?
