No data received / ERR_EMPTY_RESPONSE and no way to find the error

When I copied all files and the database to my test environment (like I have been doing in the past), I got the "No data received" error in Chrome (with ERR_EMPTY_RESPONSE).

My Dev environment works fine.

Tried visiting test environment through some proxy sites, and some aren't loading anything, others only half the (home)page.
Login page also fails to load.

I have
'debug' => array(
        'detail' => 'debug',
        'display_errors' => true
    'log' => array(
        'errors' => 1,
        'emails' => 1,
        'queries' => array(
            'log' => 0,
            'clear_on_reload' => 0

in my application/config/generated_overrides/concrete.php.

Caching is off.

Running version of C5

How can I find out what the problem is? Are there any log files?

Any news on this? I've got the same problem. I'm on Ubuntu. I've tried on Chrome and Firefox. Chrome gives the same error as above and Firefox says 'The connection was reset'.
