Blank Page After Submitting Form in Laravel

I want to add a record to my DB using Laravel but after submitting a form I get a blank screen and no logs. Here's my code:

public function store(Request $request)
    {
        foreach(Auth::user()->test as $data) {
                if($request->name == $data->name) {
                    return back()->with('wrong', trans('settings.isset.name')); 
                }
                else {
                    $this->validate($request, [
                        'name' => 'required',
                    ]);

                    $name = Name::store($request);

                    return back()->with('message', trans('settings.add.name')); 
                }
            }
    }

And there is, of course, a normal working form. Before when I didn't have foreach it was working, but not it isn't.
