Symfony change dev to prod

Question

I have the following problem, I put symfony on the server, I changed it in app_dev.php debug on false, and in app.php on true and now I should in information php bin/console about get information that I have a set version of prod, why does dev show me all the time? Of course, the debug bar will not appear, and after going under the url app_dev.php/_profiler I get an error

Error: Can not redeclare class Symfony\Component\Debug\ErrorHandler

however, after entering example.com/_profiler I get the error:

No route found for "GET /_profiler"

php bin/console about result, when i change dev to false, prod to true

Can you show your app_dev.php and your app.php? also your AppKernel, please. — fgamess
Ok because the output is saying that you are in dev environment. Is it the expected behavior? — fgamess

If you want to debug code in a production server, or something similar, I'd say there's at least a golden rule: Don't modify app_dev.php nor app.php. You can keep your prod env as usual, and meanwhile, you can run the webserver bundle with the corresponding environment (i.e. 'dev', you already have 'prod') and port. As you surely know, any changes in the code are compiled on-the-fly in dev, and in prod you have to clear the cache (and even give the proper webserver permissions). As far as I've understood, you don't want anything different to this, so I suggest revert the changes to the app*.php scripts and run the webserver bundle accordingly.

Symfony change dev to prod
