Despite of all my attempts to understand the problem, I still can't figure out what is happening. I developped a website with Symfony 2.7 which perfectly works in dev mode. When I tested it in production mode, an error 500 is returned.
The exception is :
Uncaught PHP Exception Symfony\Component\Debug\Exception\FatalErrorException:
"Error: Call to a member function getCacheFactory() on a non-object" at
/home/admdev-php/public_html/sfSUAPS/vendor/doctrine/orm/lib/Doctrine/ORM/UnitOfWork.php line 3039
{"exception":"[object] (Symfony\\Component\\Debug\\Exception\\FatalErrorException(code: 0):
Error: Call to a member function getCacheFactory() on a non-object at
/home/admdev-php/public_html/sfSUAPS/vendor/doctrine/orm/lib/Doctrine/ORM/UnitOfWork.php:3039)"} []
So I've tried to clear the cache and I had the same message :
[Symfony\Component\Debug\Exception\FatalErrorException]
Compile Error: require(): Failed opening required
'/home/stagiaire/workspace/suaps/app/cache/prod/doctrine/orm/Proxies/__CG__AppBundleEntityPlace.php'
(include_path='.:/usr/share/php:/usr/share/pear')`
I've tried to clear doctrine's cache but this doesn't solve the problem.
There are severals roles : One for students, one for teachers and one for admins. I only get this error when my role is student. So I looked closer to methods which are concerned and I commented everything related to studies and it worked. So I think the error is linked with my Entity Repository since "findBy" and "findAll" are failing.
I've took a look into Symfony's code but the error seems to be on my side. I really don't know what is going on, thank you if you can help me.
Problem solved
Turns out someone used an entity directly from cache...
