Hello,

I am a beginner in Drupal 8. I created a module following some tutorials. After I installed that module in Drupal 8 (8.0.1) version. It is creating problems with entire Drupal site. After installing that module, I am able to login as admin user, but unable to access any of the admin sections.

I am just encountering this error. "The website encountered an unexpected error. Please try again later." which is a serious issue. I checked the watchdog logs in the database. Please see the error log below:

"

| php  | a:5:{s:5:"%type";s:58:"Symfony\Component\Routing\Exception\RouteNotFoun
dException";s:8:"@message";s:37:"Route "hello.content" does not exist.";s:9:"%fu

:70:"C:\wamp\www\drupal_test\core\lib\Drupal\Core\Routing\RouteProvider.php";s:5
:"%line";i:191;} |

"

I attached my module here for further testing.

hello.content
but your code uses

hello:
  path: '/say_hello'
  defaults:

so the route name is hello

Can you please elaborate your update?

When I tried to access the '/say_hello' path, it is giving the result and the error when tried to echo in the Controller function.

Change hello: to hello.content: in your module's *.routing.yml file.

It is not possible to offer advice without seeing your code.
