문제
I just upgraded my Symfony 2.2 installation to Symfony 2.3. I was abe to get "composer update" to run with no errors, but this has caused every route in my application to return a blank page. If I check the network tab on my JavaScript console, I see that a 500 Internal Server Error is being thrown, but have no insight as to what might be causing it. Any ideas? Here's my composer.json file:

다른 팁
You need to enable it manually in 2.3.
Debug::enable();
See: https://github.com/symfony/symfony-standard/blob/2.3/UPGRADE-2.3.md
Update those lines from your composer.json thouse versions are not supported by symfony >= 2.3
Before
"jms/security-extra-bundle": "1.5.*",
"jms/di-extra-bundle": "1.4.*",
After
"jms/di-extra-bundle": "dev-master",
"jms/security-extra-bundle": "dev-master",
