Question

When there is an exception in symfony 2 it will output the following page:

Oops! An Error Occurred

The server returned a "404 Not Found".

Something is broken. Please e-mail us at [email] and let us know what you were doing when this error occurred. We will fix it as soon as possible. Sorry for any inconvenience caused.  

1. Where is the template for that page?
2. Where can I configure the email to be shown here?

EDIT:
I’m not asking how to overwrite the template as seen here:
http://symfony.com/doc/current/cookbook/controller/error_pages.html

I’m asking how to tell symfony the mail address I want it to use (assuming it’s possible), I’ve asked where is the template so I can see myself how to that, and if it’s possible.

Answer the question body not the title please!

Answer 1

As mentioned in the official manual you can overwrite templates from other bundles

All of the error templates live inside TwigBundle. To override the templates, we simply rely on the standard method for overriding templates that live inside a bundle. For more information, see Overriding Bundle Templates.
For example, to override the default error template that’s shown to the end-user, create a new template located at app/Resources/TwigBundle/views/Exception/error.html.twig:

You can find the built-in template in the source of the TwigBundle, or can directly at github. There you can see, that [email] is hardcoded.
