When you follow the answer of Anton, and still get the error, you can try the following way
At routing.yml, add this lines (only)
_welcome:
pattern: /
defaults: { _controller: AcmeDemoBundle:Welcome:index }
_demo_secured:
resource: "@AcmeDemoBundle/Controller/SecuredController.php"
type: annotation
_demo:
resource: "@AcmeDemoBundle/Controller/DemoController.php"
type: annotation
prefix: /demo
don't add this lines
_assetic:
resource: .
type: assetic
_wdt:
resource: "@WebProfilerBundle/Resources/config/routing/wdt.xml"
prefix: /_wdt
_profiler:
resource: "@WebProfilerBundle/Resources/config/routing/profiler.xml"
prefix: /_profiler
_configurator:
resource: "@SensioDistributionBundle/Resources/config/routing/webconfigurator.xml"
prefix: /_configurator
_main:
resource: routing.yml
This is an example of the routing.yml that I wrote
# Internal routing configuration to handle ESI
#_internal:
# resource: "@FrameworkBundle/Resources/config/routing/internal.xml"
# prefix: /_internal
_welcome:
pattern: /
defaults: { _controller: AcmeDemoBundle:Welcome:index }
_demo_secured:
resource: "@AcmeDemoBundle/Controller/SecuredController.php"
type: annotation
_demo:
resource: "@AcmeDemoBundle/Controller/DemoController.php"
type: annotation
prefix: /demo
