http 500 error

[jrgrafisk]

Hi

Yesterday i tried moving the hook for a module, which went terribly wrong. 
I can access the backend but the front end is HTTP 500.

I have tried turning on debug mode in /nettotruck.dk/config/defines.inc.php which doesn't work. 
I did manage to get this, when I turned on debug mode from the backend. 

Also I have tried clearing cache and disabling various modules. And of course deleting the module which hook i tried to move.

Any suggestions?

www.nettotruck.dk
v 1.7.6.0
module i tried to move: contentBox 
https://contentbox.org/?v=1.1.3

in vendor/symfony/symfony/src/Symfony/Component/HttpKernel/DataCollector/DataCollector.php (line 53)

        return $isCalledFromOverridingMethod ? $this->data : serialize($this->data);

    }

    public function unserialize($data)

    {

        $this->data = \is_array($data) ? $data : unserialize($data);

    }

    /**

     * Converts the variable into a serializable Data instance.

I had to upgrade to a newer version to fix this. 

Meant my css edits are gone, but my shop works.
